Soft Lithography - Microcontact Printing - Microtransfer Molding - Micromolding in Capillaries - AGS-TECH Inc. - NM - USA Lithography alus SOFT LITHOGRAPHY is a term used for a number of processes for pattern transfer. A master mold is needed in all cases and is microfabricated using standard lithography methods. Using the master mold, we produce an elastomeric pattern / stamp to be used in soft lithography. Elastomers used for this purpose need to be chemically inert, have good thermal stability, strength, durability, surface properties and be hygroscopic. Silicone rubber and PDMS (Polydimethylsiloxane) are two good candidate materials. These stamps can be used many times in soft lithography. One variation of soft lithography is MICROCONTACT PRINTING. The elastomer stamp is coated with an ink and pressed against a surface. The pattern peaks contact the surface and a thin layer of about 1 monolayer of the ink is transferred. This thin film monolayer acts as the mask for selective wet etching. A second variation is MICROTRANSFER MOLDING, in which the recesses of the elastomer mold are filled with liquid polymer precursor and pushed against a surface. Once the polymer cures after microtransfer molding, we peel off the mold, leaving behind the desired pattern. Lastly a third variation is MICROMOLDING IN CAPILLARIES, where the elastomer stamp pattern consists of channels that use capillary forces to wick a liquid polymer into the stamp from its side. Basically, a small amount of the liquid polymer is placed adjacent to the capillary channels and the capillary forces pull the liquid into the channels. Excess liquid polymer is removed and polymer inside the channels is allowed to cure. The stamp mold is peeled off and the product is ready. If the channel aspect ratio is moderate and the channel dimensions allowed depend on the liquid used, good pattern replication can be assured. The liquid used in micromolding in capillaries can be thermosetting polymers, ceramic sol-gel or suspensions of solids within liquid solvents. The micromolding in capillaries technique has been used in sensor manufacturing. Soft lithography is used to construct features measured on the micrometer to nanometer scale. Soft lithography has advantages over other forms of lithography like photolithography and electron beam lithography. The advantages include the following: • Lower cost in mass production than traditional photolithography • Suitability for applications in biotechnology and plastic electronics • Suitability for applications involving large or nonplanar (nonflat) surfaces • Soft lithography offers more pattern-transferring methods than traditional lithography techniques (more ''ink'' options) • Soft lithography does not need a photo-reactive surface to create nanostructures • With soft lithography we can achieve smaller details than photolithography in laboratory settings (~30 nm vs ~100 nm). The resolution depends on the mask used and can reach values down to 6 nm. MULTILAYER SOFT LITHOGRAPHY is a fabrication process in which microscopic chambers, channels, valves and vias are molded within bonded layers of elastomers. Using multilayer soft lithography devices consisting of multiple layers may be fabricated from soft materials. The softness of these materials allows the device areas to be reduced by more than two orders of magnitude compared with silicon-based devices. The other advantages of soft lithography, such as rapid prototyping, ease of fabrication, and biocompatibility, are also valid in multilayer soft lithography. We use this technique to build active microfluidic systems with on-off valves, switching valves, and pumps entirely out of elastomers. KLIK Product Finder-Locator Service PAGE sadurunge

Brazing - Soldering - Welding - Joining Processes - Assembly Services - Subassemblies - Assemblies - Custom Manufacturing - AGS-TECH Inc. - NM - USA Brazing & Soldering & Welding Among the many JOINING techniques we deploy in manufacturing, special emphasis is given to WELDING, BRAZING, SOLDERING, ADHESIVE BONDING and CUSTOM MECHANICAL ASSEMBLY because these techniques are widely used in applications like manufacturing of hermetic assemblies, high-tech product manufacturing and specialized sealing. Here we will concentrate on the more specialized aspects of these joining techniques as they are related to manufacturing of advanced products and assemblies. FUSION WELDING: We use heat to melt and coalesce materials. Heat is supplied by electricity or high-energy beams. The types of fusion welding we deploy are OXYFUEL GAS WELDING, ARC WELDING, HIGH-ENERGY-BEAM WELDING. SOLID-STATE WELDING: We join parts without melting and fusion. Our solid-state welding methods are COLD, ULTRASONIC, RESISTANCE, FRICTION, EXPLOSION WELDING and DIFFUSION BONDING. BRAZING & SOLDERING: They use filler metals and give us the advantage of working at lower temperatures than in welding, thus less structural damage to products. Information on our brazing facility producing ceramic to metal fittings, hermetic sealing, vacuum feedthroughs, high and ultrahigh vacuum and fluid control components can be found here: Brazing Factory Brochure Brazing Machines (We private label these with your brand name and logo if you wish. This way you can promote your brand name when you resell these machines to your customers) ADHESIVE BONDING: Because of the diversity of adhesives used in industry and also diversity of applications, we have a dedicated page for this. To go to our page about adhesive bonding, please click here. CUSTOM MECHANICAL ASSEMBLY: We use a variety of fasteners such as bolts, screws, nuts, rivets. Our fasteners are not limited to standard off-shelf fasteners. We design, develop and manufacture specialty fasteners that are made from nonstandard materials so they can meet requirements for special applications. Sometimes electrical or heat non-conductivity is desired whereas sometimes conductivity. For some special applications, a customer may want special fasteners that cannot be removed without destroying the product. There are endless ideas and applications. We have it all for you, if not off-shelf we can quickly develop it. To go to our page on mechanical assembly, please click here . Let us examine our various joining techniques in more details. OXYFUEL GAS WELDING (OFW): We use a fuel gas mixed with oxygen to produce the welding flame. When we use acetylene as the fuel and oxygen, we call it oxyacetylene gas welding. Two chemical reactions occur in the oxyfuel gas combustion process: C2H2 + O2 ------» 2CO + H2 + Heat 2CO + H2 + 1.5 O2--------» 2 CO2 + H2O + Heat The first reaction dissociates the acetylene into carbon monoxide and hydrogen while producing about 33% of the total heat generated. The second process above represents further combustion of the hydrogen and carbon monoxide while producing about 67% of the total heat. Temperatures in the flame are between 1533 to 3573 Kelvin. The oxygen percentage in the gas mixture is important. If the oxygen content is more than half, the flame becomes an oxidizing agent. This is undesirable for some metals but desirable for others. An example when oxidizing flame is desirable is copper-based alloys because it forms a passivation layer over the metal. On the other hand, when the oxygen content is reduced, full combustion is not possible and the flame becomes a reducing (carburizing) flame. The temperatures in a reducing flame are lower and therefore it is suitable for processes like soldering and brazing. Other gases are also potential fuels, but they have some disadvantages over acetylene. Occasionally we supply filler metals to the weld zone in the form of filler rods or wire. Some of them are coated with flux to retard oxidation of surfaces and thus protecting the molten metal. An additional benefit the flux gives us is the removal of oxides and other substances from the weld zone. This leads to stronger bonding. A variation of the oxyfuel gas welding is the PRESSURE GAS WELDING, where the two components are heated at their interface using oxyacetylene gas torch and once the interface starts to melt, the torch is withdrawn and an axial force is applied to press the two parts together until the interface is solidified. ARC WELDING: We use electrical energy to produce an arc between the electrode tip and parts to be welded. The power supply can be AC or DC while the electrodes are either consumable or nonconsumable. Heat transfer in arc welding can be expressed by the following equation: H / l = e x V I / v Here H is the heat input, l is the weld length, V and I are the voltage and current applied, v is the welding speed and e is the process efficiency. The higher the efficiency “e” the more beneficially the available energy is used to melt the material. The heat input can also be expressed as : H = u x (Volume) = u x A x l Here u is the specific energy for melting, A the cross section of the weld and l the weld length. From the two equations above we can obtain: v = e x V I / u A A variation of arc welding is the SHIELDED METAL ARC WELDING (SMAW) which constitutes about 50% of all industrial and maintenance welding processes. ELECTRIC ARC WELDING (STICK WELDING) is performed by touching the tip of a coated electrode to the workpiece and quickly withdrawing it to a distance sufficient to maintain the arc. We call this process also stick-welding because the electrodes are thin and long sticks. During the welding process, the tip of the electrode melts along with its coating and the base metal in the vicinity of the arc. A mixture of the base metal, electrode metal and substances from the electrode coating solidify in the weld area. The coating of the electrode deoxidizes and provides a shielding gas in the weld region, thus protecting it from the oxygen in the environment. Therefore the process is referred to as shielded metal arc welding. We use currents between 50 and 300 Amperes and power levels generally less than 10 kW for optimum weld performance. Also of importance is the polarity of the DC current (direction of current flow). Straight polarity where the workpiece is positive and the electrode is negative is preferred in welding of sheet metals because of its shallow penetration and also for joints with very wide gaps. When we have reverse polarity, i.e. the electrode is positive and workpiece negative we can achieve deeper weld penetrations. With AC current, since we have pulsating arcs, we can weld thick sections using large diameter electrodes and maximum currents. The SMAW welding method is suitable for workpiece thicknesses of 3 to 19 mm and even more using multiple-pass techniques. The slag formed on top of the weld needs to be removed using a wire brush, so that there is no corrosion and failure at the weld area. This of course adds to the cost of shielded metal arc welding. Nevertheless the SMAW is the most popular welding technique in industry and repair work. SUBMERGED ARC WELDING (SAW): In this process we shield the weld arc using granular flux materials like lime, silica, calcium floride, manganese oxide….etc. The granular flux is fed into the weld zone by gravity flow through a nozzle. The flux covering the molten weld zone significantly protects from sparks, fumes, UV radiation….etc and acts as a thermal insulator, thus letting heat penetrate deep into workpiece. The unfused flux is recovered, treated and reused. A coil of bare is used as electrode and fed through a tube to the area of weld. We use currents between 300 and 2000 Amperes. The submerged arc welding (SAW) process is limited to horizontal and flat positions and circular welds if rotation of the circular structure (such as pipes) is possible during welding. Speeds can reach 5 m/min. The SAW process is suitable for thick plates and results in high-quality, tough, ductile and uniform welds. The productivity, that is the amount of weld material deposited per hour is 4 to 10 times the amount as compared to the SMAW process. Another arc welding process, namely the GAS METAL ARC WELDING (GMAW) or alternatively referred to as METAL INERT GAS WELDING (MIG) is based on the weld area being shielded by external sources of gases like helium, argon, carbon dioxide….etc. There may be additional deoxidizers present in the electrode metal. Consumable wire is fed through a nozzle into the weld zone. Fabrication involving bot ferrous as well as nonferrous metals is carried out using gas metal arc welding (GMAW). Welding productivity is about 2 times that of the SMAW process. Automated welding equipment is being used. Metal is transferred in one of three ways in this process: “Spray Transfer” involves transfer of several hundred small metal droplets per second from electrode to the weld area. In “Globular Transfer” on the other hand, carbon dioxide rich gases are used and globules of molten metal are propelled by the electric arc. Welding currents are high and weld penetration deeper, welding speed greater than in spray transfer. Thus the globular transfer is better for welding heavier sections. Finally, in the “Short Circuiting” method, the electrode tip touches the molten weld pool, short circuiting it as metal at rates over 50 droplets/second is transferred in individual droplets. Low currents and voltages are used along with thinner wire. Powers used are about 2 kW and temperatures relatively low, making this method suitable for thin sheets less than 6mm thickness. Another variation the FLUX-CORED ARC WELDING (FCAW) process is similar to gas metal arc welding, except that the electrode is a tube filled with flux. The advantages of using cored-flux electrodes is that they produce more stable arcs, give us the opportunity to improve properties of weld metals, less brittle and flexible nature of its flux as compared to SMAW welding, improved welding contours. Self-shielded cored electrodes contain materials that shield the weld zone against the atmosphere. We use about 20 kW power. Like the GMAW process, the FCAW process also offers the opportunity to automate processes for continuous welding, and it is economical. Different weld metal chemistries can be developed by adding various alloys to the flux core. In ELECTROGAS WELDING (EGW) we weld the pieces placed edge to edge. It is sometimes also called BUTT WELDING. Weld metal is put into a weld cavity between two pieces to be joined. The space is enclosed by two water-cooled dams to keep the molten slag from pouring out. The dams are moved up by mechanical drives. When workpiece can be rotated, we can use the electrogas welding technique for circumferential welding of pipes too. Electrodes are fed through a conduit to keep a continuous arc. Currents can be around 400Amperes or 750 Amperes and power levels around 20 kW. Inert gases originating from either a flux-cored electrode or external source provide shielding. We use the electrogas welding (EGW) for metals such as steels, titanium….etc with thicknesses from 12mm to 75mm. The technique is a good fit for large structures. Yet, in another technique called ELECTROSLAG WELDING (ESW) the arc is ignited between the electrode and the bottom of the workpiece and flux is added. When molten slag reaches the electrode tip, the arc is extinguished. Energy is continuously supplied through the electrical resistance of the molten slag. We can weld plates with thicknesses between 50 mm and 900 mm and even higher. Currents are around 600 Ampere while voltages are between 40 – 50 V. The welding speeds are around 12 to 36 mm/min. Applications are similar to electrogas welding. One of our nonconsumable electrode processes, the GAS TUNGSTEN ARC WELDING (GTAW) also known as TUNGSTEN INERT GAS WELDING (TIG) involves the supply of a filler metal by a wire. For closely-fit joints sometimes we do not use the filler metal. In the TIG process we do not use flux, but use argon and helium for shielding. Tungsten has a high melting point and is not consumed in the TIG welding process, therefore constant current as well as arc gaps can be maintained. Power levels are between 8 to 20 kW and currents at either 200 Ampere (DC) or 500 Ampere (AC). For aluminum and magnesium we use AC current for its oxide cleaning function. To avoid contamination of the tungsten electrode, we avoid its contact with molten metals. Gas Tungsten Arc Welding (GTAW) is especially useful for welding thin metals. GTAW welds are of very high quality with good surface finish. Due to the higher cost of hydrogen gas, a less frequently used technique is ATOMIC HYDROGEN WELDING (AHW), where we generate an arc between two tungsten electrodes in a shielding atmosphere of flowing hydrogen gas. The AHW is also a nonconsumable electrode welding process. The diatomic hydrogen gas H2 breaks down into its atomic form near the welding arc where temperatures are over 6273 Kelvin. While breaking down, it absorbs large amount of heat from the arc. When the hydrogen atoms strike the weld zone which is a relatively cold surface, they recombine into diatomic form and release the stored heat. Energy can be varied by changing the workpiece to arc distance. In another nonconsumable electrode process, PLASMA ARC WELDING (PAW) we have a concentrated plasma arc directed toward the weld zone. The temperatures reach 33,273 Kelvin in PAW. A nearly equal number of electrons and ions make up the plasma gas. A low-current pilot arc initiates the plasma which is between the tungsten electrode and orifice. Operating currents are generally around 100 Amperes. A filler metal may be fed. In plasma arc welding, shielding is accomplished by an outer shielding ring and using gases such as argon and helium. In plasma arc welding, the arc may be between the electrode and workpiece or between the electrode and nozzle. This welding technique has the advantages over other methods of higher energy concentration, deeper and narrower welding capability, better arc stability, higher welding speeds up to 1 meter/min, less thermal distortion. We generally use plasma arc welding for thicknesses less than 6 mm and sometimes up to 20 mm for aluminum and titanium. HIGH-ENERGY-BEAM WELDING: Another type of fusion welding method with electron-beam welding (EBW) and laser welding (LBW) as two variants. These techniques are of particular value for our high-tech products manufacturing work. In electron-beam welding, high speed electrons strike the workpiece and their kinetic energy is converted to heat. The narrow beam of electrons travel easily in the vacuum chamber. Generally we use high vacuum in e-beam welding. Plates as thick as 150 mm can be welded. No shielding gases, flux or filler material is needed. Elecron beam guns have 100 kW capacities. Deep and narrow welds with high aspect ratios up to 30 and small heat-affected zones are possible. Welding speeds can reach 12 m/min. In laser-beam welding we use high-power lasers as the source of heat. Laser beams as small as 10 microns with high density enable deep penetration into the workpiece. Depth-to-width ratios as much as 10 is possible with laser-beam welding. We use both pulsed as well as continuous wave lasers, with the former in applications for thin materials and the latter mostly for thick workpieces up to about 25 mm. Power levels are up to 100 kW. The laser beam welding is not well suited for optically very reflective materials. Gases may also be used in the welding process. The laser beam welding method is well fit for automation & high volume manufacturing and can offer welding speeds between 2.5 m/min and 80 m/min. One major advantage this welding technique offers is access to areas where other techniques cannot be used. Laser beams can easily travel to such difficult regions. No vacuum as in electron-beam welding is needed. Welds with good quality & strength, low shrinkage, low distortion, low porosity can be obtained with laser beam welding. Laser beams can be easily manipulated and shaped using fiber optic cables. The technique is thus well suitable for welding of precision hermetic assemblies, electronic packages…etc. Let us look at our SOLID STATE WELDING techniques. COLD WELDING (CW) is a process where pressure instead of heat is applied using dies or rolls to the parts that are mated. In cold welding, at least one of the mating parts needs to be ductile. Best results are obtained with two similar materials. If the two metals to be joined with cold welding are dissimilar, we may get weak and brittle joints. The cold welding method is well suited for soft, ductile and small workpieces such as electrical connections, heat sensitive container edges, bimetallic strips for thermostats…etc. One variation of cold welding is roll bonding (or roll welding), where the pressure is applied through a pair of rolls. Sometimes we perform roll welding at elevated temperatures for better interfacial strength. Another solid state welding process we use is the ULTRASONIC WELDING (USW), where the workpieces are subjected to a static normal force and oscillating shearing stresses. The oscillating shearing stresses are applied through the tip of a transducer. Ultrasonic welding deploys oscillations with frequencies from 10 to 75 kHz. In some applications such as seam welding, we use a rotating welding disk as the tip. Shearing stresses applied to the workpieces cause small plastic deformations, break up oxide layers, contaminants and lead to solid state bonding. Temperatures involved in ultrasonic welding are way below melting point temperatures for metals and no fusion takes place. We frequently use the ultrasonic welding (USW) process for nonmetallic materials like plastics. In thermoplastics, the temperatures do reach melting points however. Another popular technique, in FRICTION WELDING (FRW) the heat is generated through friction at the interface of the workpieces to be joined. In friction welding we keep one of the workpieces stationary while the other workpiece is held in a fixture and rotated at a constant speed. The workpieces are then brought into contact under an axial force. The surface speed of rotation in friction welding may reach 900m/min in some cases. After sufficient interfacial contact, the rotating workpiece is brought to a sudden stop and the axial force is increased. The weld zone is generally a narrow region. The friction welding technique can be used to join solid and tubular parts made of a variety of materials. Some flash may develop at the interface in FRW, but this flash can be removed by secondary machining or grinding. Variations of the friction welding process exist. For example “inertia friction welding” involves a flywheel whose rotational kinetic energy is used to weld the parts. The weld is complete when the flywheel comes to a stop. The rotating mass can be varied and thus the rotational kinetic energy. Another variation is “linear friction welding”, where linear reciprocating motion is imposed on at least one of the components to be joined. In linear friction welding parts do not have to be circular, they can be rectangular, square or of other shape. Frequencies can be in the tens of Hz, amplitudes in the millimeters range and pressures in the tens or hundreds of MPa. Finally “friction stir welding” is somewhat different than the other two explained above. Whereas in inertia friction welding and linear friction welding heating of interfaces is achieved through friction by rubbing two contacting surfaces, in the friction stir welding method a third body is rubbed against the two surfaces to be joined. A rotating tool of 5 to 6 mm diameter is brought into contact with the joint. The temperatures can increase to values between 503 to 533 Kelvin. Heating, mixing and stirring of the material in the joint takes place. We use the friction stir welding on a variety of materials including aluminum, plastics and composites. Welds are uniform and quality is high with minimum pores. No fumes or spatter are produced in friction stir welding and the process is well automated. RESISTANCE WELDING (RW): The heat required for welding is produced by the electrical resistance between the two workpieces to be joined. No flux, shielding gases or consumable electrodes are used in resistance welding. Joule heating takes place in resistance welding and can be expressed as: H = (Square I) x R x t x K H is heat generated in joules (watt-seconds), I current in Amperes, R resistance in Ohms, t is the time in seconds the current flows through. The factor K is less than 1 and represents the fraction of energy that is not lost through radiation and conduction. Currents in resistance welding processes can reach levels as high as 100,000 A but voltages are typically 0.5 to 10 Volts. Electrodes are typically made of copper alloys. Both similar and dissimilar materials can be joined by resistance welding. Several variations exist for this process: “Resistance spot welding” involves two opposing round electrodes contacting the surfaces of the lap joint of the two sheets. Pressure is applied until current is turned off. The weld nugget is generally up to 10 mm in diameter. Resistance spot welding leaves slightly discolored indentation marks at weld spots. Spot welding is our most popular resistance welding technique. Various electrode shapes are used in spot welding in order to reach difficult areas. Our spot welding equipment is CNC controlled and has multiple electrodes that can be used simultaneously. Another variation “resistance seam welding” is carried out with wheel or roller electrodes that produce continuous spot welds whenever the current reaches a sufficiently high level in the AC power cycle. Joints produced by resistance seam welding are liquid and gas tight. Welding speeds of about 1.5 m/min are normal for thin sheets. One may apply intermittent currents so that spot welds are produced at desired intervals along the seam. In “resistance projection welding” we emboss one or more projections (dimples) on one of the workpiece surfaces to be welded. These projections may be round or oval. High localized temperatures are reached at these embossed spots that come into contact with the mating part. Electrodes exert pressure to compress these projections. Electrodes in resistance projection welding have flat tips and are water cooled copper alloys. The advantage of resistance projection welding is our ability to a number of welds in one stroke, thus the extended electrode life, capability to weld sheets of various thicknesses, capability to weld nuts and bolts to sheets. Disadvantage of resistance projection welding is the added cost of embossing the dimples. Yet another technique, in “flash welding” heat is generated from the arc at the ends of the two workpieces as they begin to make contact. This method may also alternatively considered arc welding. The temperature at the interface rises, and material softens. An axial force is applied and a weld is formed at the softened region. After the flash welding is complete, the joint can be machined for improved appearance. Weld quality obtained by flash welding is good. Power levels are 10 to 1500 kW. Flash welding is suitable for edge-to-edge joining of similar or dissimilar metals up to 75 mm diameter and sheets between 0.2 mm to 25 mm thickness. “Stud arc welding” is very similar to flash welding. The stud such as a bolt or threaded rod serves as one electrode while being joined to a workpiece such as a plate. To concentrate the generated heat, prevent oxidation and retain the molten metal in the weld zone, a disposable ceramic ring is placed around the joint. Finally “percussion welding” another resistance welding process, utilizes a capacitor to supply the electrical energy. In percussion welding the power is discharged within milliseconds of time very quickly developing high localized heat at the joint. We use percussion welding widely in the electronics manufacturing industry where heating of sensitive electronic components in the vicinity of the joint has to be avoided. A technique called EXPLOSION WELDING involves detonation of a layer of explosive that is put over one of the workpieces to be joined. The very high pressure exerted on the workpiece produces a turbulent and wavy interface and mechanical interlocking takes place. Bond strengths in explosive welding are very high. Explosion welding is a good method for cladding of plates with dissimilar metals. After cladding, the plates may be rolled into thinner sections. Sometimes we use explosion welding for expanding tubes so that they get sealed tightly against the plate. Our last method within the domain of solid state joining is DIFFUSION BONDING or DIFFUSION WELDING (DFW) in which a good joint is achieved mainly by diffusion of atoms across the interface. Some plastic deformation at the interface also contributes to the welding. Temperatures involved are around 0.5 Tm where Tm is melting temperature of the metal. Bond strength in diffusion welding depends on pressure, temperature, contact time and cleanliness of contacting surfaces. Sometimes we use filler metals at the interface. Heat and pressure are required in diffusion bonding and are supplied by electrical resistance or furnace and dead weights, press or else. Similar and dissimilar metals can be joined with diffusion welding. The process is relatively slow due to the time it takes for atoms to migrate. DFW can be automated and is widely used in the fabrication of complex parts for the aerospace, electronics, medical industries. Products manufactured include orthopedic implants, sensors, aerospace structural members. Diffusion bonding can be combined with SUPERPLASTIC FORMING to fabricate complex sheet metal structures. Selected locations on sheets are first diffusion bonded and then the unbonded regions are expanded into a mold using air pressure. Aerospace structures with high stiffness-to-weight ratios are manufactured using this combination of methods. The diffusion welding / superplastic forming combined process reduces the number of parts required by eliminating the need for fasteners, results in low-stress highly accurate parts economically and with short lead times. BRAZING: The brazing and soldering techniques involve lower temperatures than those required for welding. Brazing temperatures are higher than soldering temperatures however. In brazing a filler metal is placed between the surfaces to be joined and temperatures are raised to the melting temperature of the filler material above 723 Kelvin but below the melting temperatures of the workpieces. The molten metal fills the closely fitting space between workpieces. Cooling and subsequent solidification of the filer metal results in strong joints. In braze welding the filler metal is deposited at the joint. Considerably more filler metal is used in braze welding compared to brazing. Oxyacetylene torch with oxidizing flame is used to deposit the filler metal in braze welding. Due to lower temperatures in brazing, problems at heat affected zones such as warping and residual stresses are less. The smaller the clearance gap in brazing the higher is the shear strength of the joint. Maximum tensile strength however is achieved at an optimum gap (a peak value). Below and above this optimum value, the tensile strength in brazing decreases. Typical clearances in brazing can be between 0.025 and 0.2 mm. We use a variety of brazing materials with different shapes such as performs, powder, rings, wire, strip…..etc. and can manufacture these performs specially for your design or product geometry. We do also determine the content of the brazing materials according to your base materials and application. We frequently use fluxes in brazing operations to remove unwanted oxide layers and prevent oxidation. To avoid subsequent corrosion, fluxes are generally removed after the joining operation. AGS-TECH Inc. uses various brazing methods, including: - Torch Brazing - Furnace Brazing - Induction Brazing - Resistance Brazing - Dip Brazing - Infrared Brazing - Diffusion Brazing - High Energy Beam Our most common examples of brazed joints are made of dissimilar metals with good strength such as carbide drill bits, inserts, optoelectronic hermetic packages, seals. SOLDERING : This is one of our most frequently used techniques where the solder (filler metal) fills the joint as in brazing between closely fitting components. Our solders have melting points below 723 Kelvin. We deploy both manual and automated soldering in manufacturing operations. Compared to brazing, soldering temperatures are lower. Soldering is not very suitable for high-temperature or high-strength applications. We use lead-free solders as well as tin-lead, tin-zinc, lead-silver, cadmium-silver, zinc-aluminum alloys besides others for soldering. Both noncorrosive resin-based as well as inorganic acids and salts are used as flux in soldering. We use special fluxes to solder metals with low solderability. In applications where we have to solder ceramic materials, glass or graphite, we first plate the parts with a suitable metal for increased solderability. Our popular soldering techniques are: -Reflow or Paste Soldering -Wave Soldering -Furnace Soldering -Torch Soldering -Induction Soldering -Iron Soldering -Resistance Soldering -Dip soldering -Ultrasonic Soldering -Infrared Soldering Ultrasonic soldering offers us a unique advantage whereby the need for fluxes is eliminated due to ultrasonic cavitation effect which removes oxide films from the surfaces being joined. Reflow and Wave soldering are our industrially outstanding techniques for high volume manufacturing in electronics and therefore worth explaining in greater detail. In reflow soldering, we use semisolid pastes that include solder-metal particles. The paste is placed onto the joint using a screening or stenciling process. In printed circuit boards (PCB) we frequently use this technique. When electrical components are placed onto these pads from paste, the surface tension keeps the surface-mount packages aligned. After placing the components, we heat the assembly in a furnace so the reflow soldering takes place. During this process, the solvents in the paste evaporate, the flux in the paste is activated, the components are preheated, the solder particles are melted and wet the joint, and finally the PCB assembly is cooled slowly. Our second popular technique for high volume production of PCB boards, namely wave soldering relias on the fact that molten solders wet metal surfaces and form good bonds only when the metal is preheated. A standing laminar wave of molten solder is first generated by a pump and the preheated and prefluxed PCBs are conveyed over the wave. The solder wets only exposed metal surfaces but does not wet the IC polymer packages nor the polymer-coated circuit boards. A high-velocity of hot water jet blows excess solder from the joint and prevents bridging between adjacent leads. In wave soldering of surface-mount packages we first adhesively bond them to the circuit board before soldering. Again screening and stenciling is used but this time for epoxy. After the components are placed in their correct locations, the epoxy is cured, the boards are inverted and wave soldering takes place. KLIK Product Finder-Locator Service PAGE sadurunge

These downloadable files with photos and sketches will help you better understand the information we are providing you below. • CONTAINER GLASS MANUFACTURE: We have automated PRESS AND BLOW as well as BLOW AND BLOW lines for manufacturing. In the blow and blow process we drop a gob into blank mold and form the neck by applying a blow of compressed air from top. Immediately following this, compressed air is blown a second time from the other direction through the container neck to form the pre-form of the bottle. This pre-form is then transferred to the actual mold, reheated to soften and compressed air is applied to give the pre-form its final container shape. More explicitly, it is pressurized and pushed against the walls of the blow mold cavity to take its desired shape. Finally, the manufactured glass container is transfered into an annealing oven for subsequent reheating and removal of stresses produced during the molding and is cooled in a controlled fashion. In the press and blow method, molten gobs are put into a parison mold (blank mold) and pressed into the parison shape (blank shape). The blanks are then transfered to blow molds and blown similar to the process described above under “Blow and Blow Process”. Subsequent steps like annealing and stress relieve are similar or the same. • GLASS BLOWING : We have been manufacturing glass products using conventional hand blowing as well as using compressed air with automated equipment. For some orders conventional blowing is necessary, such as projects involving glass art work, or projects that require a smaller number of parts with loose tolerances, prototyping / demo projects….etc. Conventional glass blowing involves the dipping of a hollow metal pipe into a pot of molten glass and rotating the pipe for collecting some amount of the glass material. The glass collected on the tip of the pipe is rolled on flat iron, shaped as desired, elongated, re-heated and air blown. When ready, it is inserted into a mould and air is blown. The mould cavity is wet to avoid contact of the glass with metal. The water film acts like a cushion between them. Manual blowing is a labor intensive slow process and only suitable for prototyping or items of high value, not suitable for inexpensive per piece high volume orders. • MANUFACTURING OF DOMESTIC & INDUSTRIAL GLASSWARE : Using various types of glass material a large variety of glassware is being produced. Some glasses are heat resistant and suitable for laboratory glassware whereas some are good enough for withstanding dishwashers for many times and are fit for making domestic products. Using Westlake machines tens of thousands of pieces of drinking glasses are being produced per day. To simplify, molten glass is collected by vacuum and inserted into moulds to make the pre-forms. Then air is blown into the moulds, these are transfered to another mould and air is blown again and the glass takes its final shape. Like in hand blowing, these moulds are kept wet with water. Further stretching is part of the finishing operation where the neck is being formed. Excess glass is burnt off. Thereafter the controlled re-heating and cooling process described above follows. • GLASS TUBE & ROD FORMING : The main processes we use for manufacturing of glass tubes are the DANNER and VELLO processes. In the Danner Process, glass from a furnace flows and falls on an inclined sleeve made of refractory materials. The sleeve is carried on a rotating hollow shaft or blowpipe. The glass is then wrapped around the sleeve and forms a smooth layer flowing down the sleeve and over the tip of the shaft. In the case of tube forming, air is blown through a blowpipe with hollow tip, and in the case of rod forming we use solid tips on the shaft. The tubes or rods are then drawn over carrying rollers. The dimensions like wall thickness and diameter of the glass tubes are adjusted to desired values by setting the diameter of the sleeve and blowing air pressure to a desired value, adjusting the temperature, rate of flow of glass and speed of drawing. The Vello glass tube manufacturing process on the other hand involves glass that travels out a furnace and into a bowl with a hollow mandrel or bell. The glass then goes through the air space between the mandrel and the bowl and takes the shape of a tube. Thereafter it travels over rollers to a drawing machine and is cooled. At the end of the cooling line cutting and final processing takes place. The tube dimensions can be adjusted just like in the Danner process. When comparing the Danner to Vello process, we can say that Vello process is a better fit for large quantity production whereas the Danner process may be a better fit for precise smaller volume tube orders. • PROCESSING OF SHEET & FLAT & FLOAT GLASS : We have large quantities of flat glass in thicknesses ranging from submilimeter thicknesses to several centimeters. Our flat glasses are of almost optical perfection. We offer glass with special coatings such as optical coatings, where chemical vapor deposition technique is used to put coatings such as antireflection or mirror coating. Also transparent conductive coatings are common. Also available are hydrophobic or hydrophilic coatings on glass, and coating that makes glass self-cleaning. Tempered, bulletproof and laminated glasses are yet other popular items. We cut glass into desired shape with desired tolerances. Other secondary operations such as curving or bending flat glass are available. • PRECISION GLASS MOLDING : We use this technique mostly for manufacturing precision optical components without the need for more expensive and time consuming techniques like grinding, lapping and polishing. This technique is not always sufficient for making the best of the best optics, but in some cases like consumer products, digital cameras, medical optics it can be a less expensive good option for high volume manufacturing. Also it has an advantage over the other glass forming techniques where complex geometries are required, such as in the case of aspheres. The basic process involves loading of the lower side of our mold with the glass blank, evacuation of the process chamber for oxygen removal, near closing of the mold, fast and isothermal heating of die and glass with infrared light, further closing of the mould halves to press the softened glass slowly in a controlled fashion to the desired thickness, and finally cooling of the glass and filling the chamber with nitrogen and removal of the product. Precise temperature control, mould closure distance, mould closure force, matching the coefficients of expansion of the mold and glass material are key in this process. • MANUFACTURE OF GLASS OPTICAL COMPONENTS AND ASSEMBLIES : Besides precision glass molding, there are a number of valuable processes we use for making high quality optical components and assemblies for demanding applications. Grinding, lapping and polishing of optical grade glasses in fine special abrasive slurries is an art and science for making optical lenses, prisms, flats and more. Surface flatness, waviness, smoothness and defect free optical surfaces require lots of experience with such processes. Small changes in environment can result in out of specification products and bring the manufacturing line to a stop. There are cases where a single wipe on the optical surface with a clean cloth can make a product meet the specifications or fail the test. Some popular glass materials used are fused silica, quartz, BK7. Also the assembly of such components requires specialized niche experience. Sometimes special glues are being used. However, sometimes a technique called optical contacting is the best choice and involves no material in between attached optical glasses. It consists of physically contacting flat surfaces to attach to each other without glue. In some cases mechanical spacers, precision glass rods or balls, clamps or machined metal components are being used to assemble the optical components at certain distances and with certain geometric orientations to each other. Let us examine some of our popular techniques for manufacturing high end optics. GRINDING & LAPPING & POLISHING : The rough shape of the optical component is obtained with grinding a glass blank. Thereafter lapping and polishing are carried out by rotating and rubbing the rough surfaces of the optical components against tools with desired surface shapes. Slurries with tiny abrasive particles and fluid are being poured in between the optics and the shaping tools. The abrasive particle sizes in such slurries can be chosen according to the degree of flatness desired. The deviations of critical optical surfaces from desired shapes are expressed in terms of wavelengths of the light being used. Our high precision optics have tenth of a wavelength (Wavelength/10) tolerances or even tighter is possible. Besides surface profile, the critical surfaces are scanned and evaluated for other surface features and defects such as dimensions, scratches, chips, pits, specks...etc. The tight control of environmental conditions in the optical manufacturing floor and extensive metrology and testing requirements with state-of-the-art equipment make this a challenging branch of industry. • SECONDARY PROCESSES IN GLASS MANUFACTURING: Again, we are only limited with your imagination when it comes to secondary and finishing processes of glass. Here we list some of them: -Coatings on glass (optical, electrical, tribological, thermal, functional, mechanical...). As an example we can alter surface properties of glass making it for example reflect heat so that it keeps building interiors cool, or make one side infrared absorbing using nanotechnology. This helps keep the inside of buildings warm because the outermost surface layer of glass will absorb the infrared radiation inside the building and radiate it back to the inside. -Etching on glass -Applied Ceramic Labeling (ACL) -Engraving -Flame polishing -Chemical polishing -Staining MANUFACTURING OF TECHNICAL CERAMICS • DIE PRESSING : Consists of uniaxial compaction of granular powders confined in a die • HOT PRESSING : Similar to die pressing but with the addition of temperature to enhance densification. Powder or compacted preform is placed into graphite die and uniaxial pressure is applied while the die is kept at high temperatures such as 2000 C. Temperatures can be different depending on the type of ceramic powder being processed. For complicated shapes and geometries other subsequent processing such as diamond grinding may be needed. • ISOSTATIC PRESSING : Granular powder or die pressed compacts are placed in airtight containers and then into a closed pressure vessel with liquid inside. Thereafter they are compacted by increasing the pressure vessel’s pressure. The liquid inside the vessel transfers the pressure forces uniformly over the entire surface area of the airtight container. The material is thus compacted uniformly and takes the shape of its flexible container and its internal profile and features. • HOT ISOSTATIC PRESSING : Similar to isostatic pressing, but in addition to pressurized gas atmosphere, we sinter the compact at high temperature. Hot isostatic pressing results in additional densification and increased strength. • SLIP CASTING / DRAIN CASTING : We fill the mould with a suspension of micrometer sized ceramic particles and carrier liquid. This mixture is called “slip”. The mould has pores and therefore the liquid in the mixture is filtered into the mould. As a result, a cast is formed on the inner surfaces of the mould. After sintering, the parts can be taken out of the mould. • TAPE CASTING : We manufacture ceramic tapes by casting ceramic slurries onto flat moving carrier surfaces. The slurries contain ceramic powders mixed with other chemicals for binding and carrying purposes. As the solvents evaporate dense and flexible sheets of ceramic are left behind which can be cut or rolled as desired. • EXTRUSION FORMING : As in other extrusion processes, a soft mixture of ceramic powder with binders and other chemicals is passed through a die to acquire its cross-sectional shape and is then cut at desired lengths. The process is performed with cold or heated ceramic mixtures. • LOW PRESSURE INJECTION MOLDING : We prepare a mixture of ceramic powder with binders and solvents and heat it to a temperature where it can easily be pressed and forced into the tool cavity. Once the moulding cycle is complete, the part is ejected and the binding chemical is burned off. Using injection molding, we can obtain intricate parts at high volumes economically. Holes that are a tiny fraction of a milimeter on a 10mm thick wall are possible, threads are possible without forther machining, tolerances as tight as +/- 0.5% are possible and even lower when parts are machined, wall thicknesses in the order of 0.5mm to a length of 12.5 mm are possible as well as wall thicknesses of 6.5mm to a length of 150mm. • GREEN MACHINING : Using the same metal machining tools, we can machine pressed ceramic materials while they are still soft like chalk. Tolerances of +/- 1% are possible. For better tolerances we use diamond grinding. • SINTERING or FIRING : Sintering makes full densification possible. Significant shrinkage occurs on the green compact parts, but this is not a big problem since we take into account these dimensional changes when we design the part and tooling. Powder particles are bonded together and porosity induced by the compaction process is removed to great extent.. • DIAMOND GRINDING : The World’s hardest material “diamond” is being used to grind hard materials like ceramics and precision parts are obtained. Tolerances in the micrometer range and very smooth surfaces are being achieved. Due to its expense, we only consider this technique when we really need it. • HERMETIC ASSEMBLIES are those that practically speaking do not allow any exchange of matter, solids, liquids or gases between interfaces. Hermetic sealing is airtight. For example hermetic electronic enclosures are those that keep the sensitive interior contents of a packaged device unharmed by moisture, contaminants or gases. Nothing is 100% hermetic, but when we speak of hermeticity we mean that in practical terms, that there is hermeticity to the extent that the leak rate is so low that the devices are safe under normal environmental conditions for very long times. Our hermetic assemblies consist of metal, glass and ceramic components, metal-ceramic, ceramic-metal-ceramic, metal-ceramic-metal, metal to metal, metal-glass, metal-glass-metal, glass-metal-glass, glass-metal and glass to glass and all other combinations of metal-glass-ceramic bonding. We can for example metal coat the ceramic components so they can be strongly bonded to other components in the assembly and have excellent sealing capability. We have the know-how of coating optical fibers or feedthroughs with metal and soldering or brazing them to the enclosures, so no gases pass or leak into the enclosures. Therefore they are used for manufacturing electronic enclosures to encapsulate sensitive devices and protect them from the outer atmosphere. Besides their excellent sealing characteristics, other properties such as the thermal expansion coefficient, deformation resistance, non-outgassing nature, very long lifetime, nonconductive nature, thermal insulation properties, antistatic nature...etc. make glass and ceramic materials the choice for certain applications.

Please click on the links below to select the filtration product of your interest. Activated Carbon Filters Activated carbon also called activated charcoal, is a form of carbon processed to have small, low-volume pores that increase the surface area available for adsorption or chemical reactions. Due to its high degree of microporosity, just one gram of activated carbon has a surface area in excess of 1,300 m2 (14,000 sq ft). An activation level sufficient for useful application of activated carbon may be attained solely from high surface area; however, further chemical treatment often enhances adsorption properties. Activated carbon is widely used in filters for gas purification, filters for decaffeination, metal extraction & purification, filtration & purification of water, medicine, treatment of sewage, air filters in gas masks and respirators, compressed air filters, filtering of alcoholic beverages like vodka and whiskey from organic impurities which can affect taste, odor and color among many other applications. Activated carbon is being used in various types of filters, most commonly in panel filters, non-woven fabric, cartridge type filters....etc. You can download brochures of our activated carbon filters from the links below. - Air Purification Filters (includes folded type and V-shaped Activated Carbon Air Filters) Ceramic Membrane Filters Ceramic membrane filters are inorganic, hydrophilic, and are ideal for extreme nano-, ultra-, and micro-filtration applications that require longevity, superior pressure/temperature tolerances and resistance to aggressive solvents. Ceramic membrane filters are basically ultra-filtration or micro-filtration filters, used to treat wastewater and water at higher elevated temperatures. Ceramic membrane filters are produced from inorganic materials such as aluminum oxide, silicon carbide, titanium oxide, and zirconium oxide. The membrane porous core material is first formed through extrusion process which becomes the support structure for the ceramic membrane. Then coatings are applied to the inner face or the filtering face with the same ceramic particles or sometimes different particles, depending on the application. For example, if your core material is aluminum oxide, we also use aluminum oxide particles as the coating. The size of ceramic particles used for the coating, as well as the number of coating applied will determine the pore size of the membrane as well as the distribution characteristics. After depositing the coating to the core, high-temperature sintering takes place inside a furnace, making the membrane layer integral of the core support structure. This provides us a very durable and hard surface. This sintered bonding ensures a very long life for the membrane. We can custom manufacture ceramic membrane filters for you from micro-filtration range to ultra-filtration range by varying the number of coatings and by using the right particle size for the coating. Standard pore sizes can vary from 0.4 microns to .01 micron size. Ceramic membrane filters are like glass, very hard and durable, unlike polymeric membranes. Therefore ceramic membrane filters offer a very high mechanical strength. Ceramic membrane filters are chemically inert, and they can be used at a very high flux compared to polymeric membranes. Ceramic membrane filters can be vigorously cleaned and are thermally stable. Ceramic membrane filters have a very long operational life, roughly three to four times as long compared to the polymeric membranes. Compared to polymeric filters, ceramic filters are very expensive, because ceramic filtration applications start where the polymeric applications end. Ceramic membrane filters have various applications, mostly in treating very difficult to treat water and wastewater, or where high temperature operations are involved. It also has vast applications in oil and gas, wastewater recycling, as a pre‑treatment for RO, and for removing precipitated metals from any precipitation process, for oil & water separation, food and beverage industry, microfiltration of milk, clarification of fruit juice, reclamation and collection of nano powders and catalyzers, in the pharmaceutical industry, in mining where you have to treat the wasted tailing ponds. We offer single channel as well as multiple channel shaped ceramic membrane filters. Both off-the-shelf as well as custom manufacturing is offered to you by AGS-TECH Inc. Ceramic Foam Filters Ceramic foam filter is a tough foam made from ceramics . Open-cell polymer foams are internally impregnated with ceramic slurry and then fired in a kiln , leaving only ceramic material. The foams may consist of several ceramic materials such as aluminium oxide , a common high-temperature ceramic. Ceramic foam filters get insulating properties from the many tiny air-filled voids within the material. Ceramic foam filters are used for filtration of molten metal alloys, absorption of environmental pollutants , and as substrate for catalysts requiring large internal surface area. Ceramic foam filters are hardened ceramics with pockets of air or other gases trapped in pores throughout the body of the material. These materials can be fabricated as high as 94 to 96% air by volume with high temperature resistances such as 1700 °C. Since most ceramics are already oxides or other inert compounds, there is no danger of oxidation or reduction of the material in ceramic foam filters. - Ceramic Foam Filters Brochure - Ceramic Foam Filter User's Guide HEPA Filters HEPA is a type of air filter and the abbreviation stands for High-Efficiency Particulate Arrestance (HEPA). Filters meeting the HEPA standard have many applications in clean rooms, medical facilities, automobiles, aircraft and homes. HEPA filters must satisfy certain standards of efficiency such as those set by the United States Department of Energy (DOE). To qualify as HEPA by US government standards, an air filter must remove from the air that passes through 99.97% of particles that are sized 0.3 µm. HEPA filter's minimal resistance to airflow, or pressure drop, is generally specified as 300 pascals (0.044 psi) at its nominal flow rate. HEPA filtration works by mechanical means and does not resemble the Ionic and Ozone filtration methods which use negative ions and ozone gas respectively. Therefore, the chances of potential pulmonary side-effects like asthma and allergies is much lower with HEPA filtering systems. HEPA filters are also used in high quality vacuum cleaners effectively to protect users from asthma and allergies, because HEPA filter traps fine particles such as pollens and dust mite feces which trigger allergy and asthma symptoms. Contact us if you would like to get our opinion about using HEPA filters for a particular application or project. You can download our product brochures for off-the-shelf HEPA filters below. If you cannot find the right size or shape you would need we will be happy to design and manufacture custom HEPA filters for your special application. - Air Purification Filters (includes HEPA Filters) - Private Label Industrial Filters (We can put your company name and logo on these filters. Includes also HEPA filters) Coarse Filters & Pre-Filtering Media Coarse filters and pre-filtering media are used to block large debris. They are of critical importance because they are inexpensive and protect the more expensive higher grade filters from being contaminated with coarse particulates and contaminants. Without coarse filters and pre-filtering media, the cost of filtering would have been much much higher as we would need to change fine filters much more frequently. Most of our coarse filters and pre-filtering media are made of synthetic fibers with controlled diameters and pore sizes. Coarse filter materials include the popular material polyester. Filtering efficiency grade is an important parameter to check for before choosing a particular coarse filter / pre-filtering media. Other parameters and features to check for are whether the pre-filtering media is washable, reusable, arrestance value, resistance against air or fluid flow, rated air flow, dust and particulate holding capacity, temperature resistance, flammability, pressure drop characteristics, dimensional and shape related specification...etc. Contact us for opinion before choosing the right coarse filters & pre-filtering media for your products and systems. - Wire Mesh and Cloth Brochure (includes information on our wire mesh & cloth filters manufacturing capabilities.

Such things may be molecules, ions, or other small particles. Generally, polymeric membranes are used to separate, concentrate, or fractionate a wide variety of liquids. Membranes serve as a thin barrier between miscible fluids that allow for preferential transport of one or more feed components when a driving force is applied, such as a pressure differential. We offer a suite of nanofiltration, ultrafiltration and microfiltration membranes that are engineered to provide optimal flux and rejection and can be customized to meet the unique requirements of specific process applications. Membrane filtration systems are the heart of many separation processes. Technology selection, equipment design, and fabrication quality are all critical factors in the ultimate success of a project. To start, the proper membrane configuration must be selected. Contact us for help in your projects. PAGE sadurunge

Functional & Decorative Coatings, Thin Film, Thick Films, Antireflective and Reflective Mirror Coating - AGS-TECH Inc. Lapisan Fungsional / Lapisan Dekoratif / Film Tipis / Film Tebal A COATING is a covering that is applied to the surface of an object. Coatings can be in the form of THIN FILM (less than 1 micron thick) or THICK FILM (over 1 micron thick). Based on the purpose of applying the coating we can offer you DECORATIVE COATINGS and/or FUNCTIONAL COATINGS, or both. Sometimes we apply functional coatings to change the surface properties of the substrate, such as adhesion, wettability, corrosion resistance, or wear resistance. In some other cases such as in semiconductor device fabrication, we apply the functional coatings to add a completely new property such as magnetization or electrical conductivity which become an essential part of the finished product. Our most popular FUNCTIONAL COATINGS are: Adhesive Coatings: Examples are adhesive tape, iron-on fabric. Other functional adhesive coatings are applied to change the adhesion properties, such as non-stick PTFE coated cooking pans, primers that encourage subsequent coatings to adhere well. Tribological Coatings: These functional coatings relate to the principles of friction, lubrication and wear. Any product where one material slides or rubs over another is affected by complex tribological interactions. Products like hip implants and other artificial prosthesis are lubricated in certain ways whereas other products are unlubricated as in high temperature sliding components where conventional lubricants can not be used. The formation of compacted oxide layers have been proven to protect against wear of such sliding mechanical parts. Tribological functional coatings have huge benefits in industry, minimizing wear of machine elements, minimizing wear and tolerance deviations in manufacturing tools such as dies and moulds, minimizing power requirements and making machinery and equipment more energy efficient. Optical Coatings: Examples are Anti-reflective (AR) coatings, reflective coatings for mirrors, UV- absorbent coatings for protection of eyes or for increasing the life of the substrate, tinting used in some colored lighting, tinted glazing and sunglasses. Catalytic Coatings such as applied on self-cleaning glass. Light-Sensitive Coatings used to make products such as photographic films Protective Coatings: Paints can be considered protecting the products besides being decorative in purpose. Hard anti-scratch coatings on plastics and other materials are one of our most widely used functional coatings to reduce scratching, improve wear resistance, …etc. Anti-corrosion coatings such as plating are also very popular. Other protective functional coatings are put on waterproof fabric and paper, antimicrobial surface coatings on surgical tools and implants. Hydrophilic / Hydrophobic Coatings: Wetting (hydrophilic) and unwetting (hydrophobic) functional thin and thick films are important in applications where water absorption is either desired or undesired. Using advanced technology we can alter your product surfaces, to make them either easily wettable or unwettable. Typical applications are in textiles, dressings, leather boots, pharmaceutical or surgical products. Hydrophilic nature refers to a physical property of a molecule that can transiently bond with water (H2O) through hydrogen bonding. This is thermodynamically favorable, and makes these molecules soluble not only in water, but also in other polar solvents. Hydrophilic and hydrophobic molecules are also known as polar molecules and nonpolar molecules, respectively. Magnetic Coatings: These functional coatings add magnetic properties such as is the case for magnetic floppy disks, cassettes, magnetic stripes, magnetooptic storage, inductive recording media, magnetoresist sensors, and thin-film heads on products. Magnetic thin films are sheets of magnetic material with thicknesses of a few micrometers or less, used primarily in the electronics industry. Magnetic thin films can be single-crystal, polycrystalline, amorphous, or multilayered functional coatings in the arrangement of their atoms. Both ferro- and ferrimagnetic films are used. The ferromagnetic functional coatings are usually transition-metal-based alloys. For example, permalloy is a nickel-iron alloy. The ferrimagnetic functional coatings, such as garnets or the amorphous films, contain transition metals such as iron or cobalt and rare earths and the ferrimagnetic properties are advantageous in magnetooptic applications where a low overall magnetic moment can be achieved without a significant change in the Curie temperature. Some sensor elements function on the principle of change in electrical properties, such as the electrical resistance, with a magnetic field. In semiconductor technology, the magnetoresist head used in disk storage technology functions with this principle. Very large magnetoresist signals (giant magnetoresistance) are observed in magnetic multilayers and composites containing a magnetic and nonmagnetic material. Electrical or Electronic Coatings: These functional coatings add electrical or electronic properties such as conductivity to manufacture products such as resistors, insulation properties such as in the case of magnet wire coatings used in transformers. DECORATIVE COATINGS: When we speak of decorative coatings the options are only limited by your imagination. Both thick and thin film type coatings have been successfully engineered and applied in the past to our customers products. Regardless of the difficulty in the geometric shape and material of the substrate and application conditions, we are always capable to formulate the chemistry, physical aspects such as exact Pantone code of color and application method for your desired decorative coatings. Complex patterns involving shapes or different colors are also possible. We can make your plastic polymer parts look metallic. We can color anodize extrusions with various patterns and it won’t even look anodized. We can mirror coat an oddly-shaped part. Furthermore decorative coatings can be formulated that will also act as functional coatings at the same time. Any of the below mentioned thin and thick film deposition techniques used for functional coatings can be deployed for decorative coatings. Here are some of our popular decorative coatings: - PVD Thin Film Decorative Coatings - Electroplated Decorative Coatings - CVD and PECVD Thin Film Decorative Coatings - Thermal Evaporation Decorative Coatings - Roll-to-Roll Decorative Coating - E-Beam Oxide Interference Decorative Coatings - Ion Plating - Cathodic Arc Evaporation for Decorative Coatings - PVD + Photolithography, Heavy Gold Plating on PVD - Aerosol Coatings for Glass Coloring - Anti-tarnish Coating - Decorative Copper-Nickel-Chrome Systems - Decorative Powder Coating - Decorative Painting, Custom Tailored Paint Formulations using Pigments, Fillers, Colloidal Silica Dispersant...etc. If you contact us with your requirements for decorative coatings, we can provide you our expert opinion. We have advanced tools such as color readers, color comparators….etc. to guarantee consistent quality of your coatings. THIN and THICK FILM COATING PROCESSES: Here are the most widely used of our techniques. Electro-Plating / Chemical Plating (hard chromium, chemical nickel) Electroplating is the process of plating one metal onto another by hydrolysis, for decorative purposes, corrosion prevention of a metal or other purposes. Electroplating lets us use inexpensive metals such as steel or zinc or plastics for the bulk of the product and then apply different metals on the outside in the form of a film for better appearance, protection, and for other properties desired for the product. Electroless plating, also known as chemical plating, is a non-galvanic plating method that involves several simultaneous reactions in an aqueous solution, which occur without the use of external electrical power. The reaction is accomplished when hydrogen is released by a reducing agent and oxidized, thus producing a negative charge on the surface of the part. Advantages of these thin and thick films are good corrosion resistance, low processing temperature, possibility to deposit in bore holes, slots… etc. Disadvantages are the limited selection of coating materials, relatively soft nature of the coatings, environmentally polluting treatment baths that are needed including chemicals such as cyanide, heavy metals, fluorides, oils, limited accuracy of surface replication. Diffusion Processes (Nitriding, nitrocarburization, boronizing, phosphating, etc.) In heat treatment furnaces, the diffused elements usually originate from gases reacting at high temperatures with the metal surfaces. This can be a pure thermal and chemical reaction as a consequence of the thermal dissociation of the gases. In some cases, diffused elements originate from solids. The advantages of these thermochemical coating processes are good corrosion resistance, good reproducibility. The disadvantages of these are being relatively soft coatings, limited selection of base material (which must be suitable for nitriding), long processing times, environmental and health hazards involved, requirement of post-treatment. CVD (Chemical Vapor Deposition) CVD is a chemical process used to produce high quality, high-performance, solid coatings. The process produces thin films too. In a typical CVD, the substrates are exposed to one or more volatile precursors, that react and/or decompose on the substrate surface to produce the desired thin film. Advantages of these thin & thick films are their high wear resistance, potential to economically produce thicker coatings, suitability for bore holes, slots ….etc. Disadvantages of CVD processes are their high processing temperatures, difficulty or impossibility of coatings with multiple metals (such as TiAlN), rounding of edges, use of environmentally hazardous chemicals. PACVD / PECVD (Plasma-Assisted Chemical Vapor Deposition) PACVD is also called PECVD standing for Plasma Enhanced CVD. Whereas in a PVD coating process the thin & thick film materials are evaporated from a solid form, in PECVD the coating results from a gas phase. Precursor gasses are cracked in the plasma to become available for the coating. Advantages of this thin and thick film deposition technique is that significantly lower process temperatures are possible as compared to CVD, precise coatings are deposited. Disadvantages of PACVD are that it has only limited suitability for bore holes, slots etc. PVD (Physical Vapor Deposition) PVD processes are a variety of purely physical vacuum deposition methods used to deposit thin films by the condensation of a vaporized form of the desired film material onto workpiece surfaces. Sputtering and evaporative coatings are examples of PVD. Advantages are that no environmentally damaging materials and emissions are produced, a large variety of coatings can be produced, coating temperatures are below the final heat treatment temperature of most steels, precisely reproducible thin coatings, high wear resistance, low frictional coefficient. Disadvantages are bore holes, slots ...etc. can only be coated down to a depth equal to the diameter or width of the opening, corrosion resistant only under certain conditions, and for obtaining uniform film thicknesses, parts must be rotated during deposition. The adhesion of functional and decorative coatings are substrate dependent. Furthermore, the lifetime of thin and thick film coatings depends on environmental parameters such as humidity, temperature...etc. Therefore, before considering a functional or decorative coating, contact us for our opinion. We can choose the most suitable coating materials and coating technique that fits your substrates and application and deposit them under the strictest quality standards.

It will be our pleasure to briefly summarize and provide information about the main concepts in the realm of FIBER OPTIC TESTING. FIBER STRIPPING & CLEAVING & SPLICING : There are two major types of splicing, FUSION SPLICING and MECHANICAL SPLICING. In industry and high volume manufacturing, fusion splicing is the most widely used technique as it provides for the lowest loss and least reflectance, as well as providing the strongest and most reliable fiber joints. Fusion splicing machines can splice a single fiber or a ribbon of multiple fibers at one time. Most single mode splices are fusion type. Mechanical splicing on the other hand is mostly used for temporary restoration and mostly for multimode splicing. Fusion splicing requires higher capital expenses as compared to mechanical splicing because it requires a fusion splicer. Consistent low loss splices can only be achieved using proper techniques and keeping equipment in good condition. Cleanliness is vital. FIBER STRIPPERS should be kept clean and in good condition and be replaced when nicked or worn. FIBER CLEAVERS are also vital for good splices as one has to have good cleaves on both fibers. Fusion splicers need proper maintenance and fusing parameters need to be set for the fibers being spliced. OTDR & OPTICAL TIME DOMAIN REFLECTOMETER : This instrument is used to test the performance of new fiber optic links and detect problems with existing fiber links. OTDR traces are graphical signatures of a fiber's attenuation along its length. The optical time domain reflectometer (OTDR) injects an optical pulse into one end of the fiber and analyzes the returning backscattered and reflected signal. A technician at one end of the fiber span can measure and localize attenuation, event loss, reflectance, and optical return loss. Examining non-uniformities in the OTDR trace we can evaluate the performance of the link components such as cables, connectors and splices as well as the quality of the installation. Such fiber tests assure us that the workmanship and quality of the installation meet the design and warranty specifications. OTDR traces help characterize individual events that can often be invisible when conducting only loss/length testing. Only with a complete fiber certification, installers can fully understand the quality of a fiber installation. OTDRs are also used for testing and maintaining fiber plant performance. OTDR allows us to see more details impacted by the cabling installation. OTDR maps the cabling and can illustrate termination quality, location of faults. An OTDR provides advanced diagnostics to isolate a point of failure that may hinder network performance. OTDRs allow discovery of problems or potential problems along the length of a channel that may affect long term reliability. OTDRs characterize features such as attenuation uniformity and attenuation rate, segment length, location and insertion loss of connectors and splices, and other events such as sharp bends that may have been incurred during installation of cables. An OTDR detects, locates, and measures events on fiber links and requires access to only one end of the fiber. Here is a summary of what a typical OTDR can measure: Attenuation (also known as fiber loss): Expressed in dB or dB/km, attenuation represents the loss or the rate of loss between two points along the fiber span. Event Loss: The difference in the optical power level before and after an event, expressed in dB. Reflectance: The ratio of reflected power to incident power of an event, expressed as a negative dB value. Optical Return Loss (ORL): The ratio of the reflected power to the incident power from a fiber optic link or system, expressed as a positive dB value. OPTICAL POWER METERS : These meters measure average optical power out of an optical fiber. Removable connector adapters are used in optical power meters so that various models of fiber optic connectors can be used. Semiconductor detectors inside power meters have sensitivities that vary with the wavelength of light. Therefore they are calibrated at typical fiber optic wavelengths such as 850, 1300 and 1550 nm. Plastic Optical Fiber or POF meters on the other hand are calibrated at 650 and 850 nm. Power meters are sometimes calibrated to read in dB (Decibel) referenced to one miliwatt of optical power. Some power meters however are calibrated in relative dB scale, which is well suited for loss measurements because the reference value may be set to “0 dB” on the output of the test source. Rare but occasionally lab meters measure in linear units such as miliwatts, nanowatts….etc. Power meters cover a very broad dynamic range 60 dB. However most optical power and loss measurements are made in the range 0 dBm to (-50 dBm). Special power meters with higher power ranges of up to +20 dBm are used for testing fiber amplifiers and analog CATV systems. Such higher power levels are needed to assure the proper functioning of such commercial systems. Some laboratory type meters on the other hand can measure at very low power levels down to (-70 dBm) or even lower, because in research and development engineers frequently have to deal with weak signals. Continuous wave (CW) test sources are used frequently for loss measurements. Power meters measure the time average of the optical power instead of the peak power. Fiber optic power meters should be recalibrated frequently by labs with NIST traceable calibration systems. Regardless of price, all power meters have similar inaccuracies typically in the neighborhood of +/-5%. This uncertainty is caused by the variability in coupling efficiency at the adapters/connectors, reflections at polished connector ferrules, unknown source wavelengths, nonlinearities in electronic signal conditioning circuitry of the meters and detector noise at low signal levels. FIBER OPTIC TEST SOURCE / LASER SOURCE : An operator needs a test source as well as a FO power meter in order to make measurements of optical loss or attenuation in fibers, cables and connectors. The test source must be chosen for compatibility with the type of fiber in use and the wavelength desired for performing the test. Sources are either LED's or lasers similar to those used as transmitters in actual fiber optic systems. LED's are generally used for testing multimode fiber and lasers for singlemode fibers. For some tests such as measuring spectral attenuation of fiber, a variable wavelength source is used, which is usually a tungsten lamp with a monochromator to vary the output wavelength. OPTICAL LOSS TEST SETS : Sometimes also refered to as ATTENUATION METERS, these are instruments made of fiber optic power meters and sources which are used to measure the loss of fibers, connectors and connectorized cables. Some optical loss test sets have individual source outputs and meters like a separate power meter and test source, and have two wavelengths from one source output (MM: 850/1300 or SM:1310/1550) Some of them offer bidirectional testing on a single fiber and some have two bidirectional ports. The combination instrument which contains both a meter and a source may be less convenient than an individual source and power meter. This is the case when the ends of the fiber and cable are usually separated by long distances, which would require two optical loss test sets instead of one source and one meter. Some instruments also have a single port for bidirectional measurements. VISUAL FAULT LOCATOR : These are simple instruments that inject visible wavelength light into the system and one can visually trace the fiber from transmitter to receiver to insure correct orientation and continuity. Some visual fault locators have powerful visible light sources such as a HeNe laser or visible diode laser and therefore high loss points can be made visible. Most applications center around short cables such as used in telecommunication central offices to connect to the fiber optic trunk cables. Since the visual fault locator covers the range where OTDRs are not useful, it is complementary instrument to the OTDR in cable troubleshooting. Systems with powerful light sources will work on buffered fiber and jacketed single fiber cable if the jacket is not opaque to the visible light. The yellow jacket of singlemode fibers and orange jacket of multimode fibers will usually pass the visible light. With most multifiber cables this instrument cannot be used. Many cable breaks, macrobending losses caused by kinks in the fiber, bad splices….. can be detected visually with these instruments. These instruments have a short range, typically 3-5 km, due to high attenuation of visible wavelengths in fibers. FIBER IDENTIFIER : Fiber Optic technicians need to identify a fiber in a splice closure or at a patch panel. If one carefully bends a singlemode fiber enough to cause loss, the light that couples out can also be detected by a large area detector. This technique is used in fiber identifiers to detect a signal in the fiber at transmission wavelengths. A fiber identifier generally functions as a receiver, is able to discriminate between no signal, a high speed signal and a 2 kHz tone. By specifically looking for a 2 kHz signal from a test source that is coupled into the fiber, the instrument can identify a specific fiber in a large multifiber cable. This is essential in fast and speedy splicing and restoration processes. Fiber identifiers can be used with buffered fibers and jacketed single fiber cables. FIBER OPTIC TALKSET : Optical talk sets are useful for fiber installation and testing. They transmit voice over fiber optic cables that are installed and allow the technician splicing or testing the fiber to communicate effectively. Talksets are even more useful when walkie-talkies and telephones are not available in remote locations where splicing is being done and in buildings with thick walls where radio waves will not penetrate through. Talksets are most effectively used by setting up the talksets on one fiber and leaving them in operation while testing or splicing work is done. This way there will always be a communications link between the work crews and will facilitate deciding which fibers to work with next. The continuous communications capability will minimize misunderstandings, mistakes and will speed up the process. Talksets include those for networking multi-party communications, especially helpful in restorations, and system talksets for use as intercoms in installed systems. Combination testers and talksets are also available commercially. To this date, unfortunately different manufacturers' talksets can not communicate with each other. VARIABLE OPTICAL ATTENUATOR : Variable Optical Attenuators allow the technician to manually vary the attenuation of the signal in the fiber as it is transmitted through the device. VOAs can be used to balance the signal strengths in fiber circuits or to balance an optical signal when evaluating the dynamic range of the measurement system. Optical attenuators are commonly used in fiber optic communications to test power level margins by temporarily adding a calibrated amount of signal loss, or installed permanently to properly match transmitter and receiver levels. There are fixed, step-wise variable, and continuously variable VOAs commercially available. Variable optical test attenuators generally use a variable neutral density filter. This offers the advantages of being stable, wavelength insensitive, mode insensitive, and a large dynamic range. A VOA may be either manually or motor controlled. Motor control provides users a distinct productivity advantage, since commonly used test sequences can be run automatically. The most accurate variable attenuators have thousands of calibration points, resulting in excellent overall accuracy. INSERTION / RETURN LOSS TESTER : In fiber optics, Insertion Loss is the loss of signal power resulting from the insertion of a device in a transmission line or optical fiber and is usually expressed in decibels (dB). If the power transmitted to the load before insertion is PT and the power received by the load after insertion is PR, then the insertion loss in dB is given by: IL = 10 log10(PT/PR) Optical Return Loss is the ratio of the light reflected back from a device under test, Pout, to the light launched into that device, Pin, usually expressed as a negative number in dB. RL = 10 log10(Pout/Pin) Loss may be caused by reflections and scattering along the fiber network due to contributors such as dirty connectors, broken optical fibers, poor connector mating. Commercial optical return loss (RL) & insertion loss (IL) testers are high performance loss test stations that are designed specially for optical fibre testing, lab testing and passive components production. Some integrate three different tests modes in one test station, working as a stable laser source, optical power meter and a return loss meter. The RL and IL measurements are displayed on two separate LCD screens, whilst in return loss test model, the unit will automatically and synchronously set the same wavelength for the light source and power meter. These instruments come complete with FC, SC, ST and universal adaptors. E1 BER TESTER : Bit error rate (BER) tests allow technicians to test cables and diagnose signal problems in the field. One can configure individual T1 channel groups to run an independent BER test, set one local serial port to Bit error rate test (BERT) mode while the remaining local serial ports continue to transmit and receive normal traffic. The BER test checks communication between the local and the remote ports. When running a BER test, the system expects to receive the same pattern that it is transmitting. If traffic is not being transmitted or received, technicians create a back-to-back loopback BER test on the link or in the network, and send out a predictable stream to ensure that they receive the same data that was transmitted. To determine whether the remote serial port returns the BERT pattern unchanged, technicians must manually enable network loopback at the remote serial port while they configure a BERT pattern to be used in the test at specified time intervals on the local serial port. Later they can display and analyze the total number of error bits transmitted and the total number of bits received on the link. Error statistics can be retrieved anytime during the BER test. AGS-TECH Inc. offers E1 BER (Bit Error Rate) testers that are compact, multi-functional and handheld instruments, specially designed for R&D, production, installation and maintenance of SDH, PDH, PCM, and DATA protocol conversion.
