Abstract: Disclosed is a method and solution for providing corrosion protection for electrical contact members. The contact members are exposed to the solution, which in one embodiment includes a phosphonate, a lubricant, and a solvent. In a preferred embodiment, the phosphonate is phosphonic acid, the lubricant is polyphenyl ether or tricresylphosphate, and the solvent includes an isoparaffinic hydrocarbon. In a further embodiment, the lubricant can be omitted from the solution.

Abstract: Disclosed is a method for fabricating devices, and the resulting products, using Tape Automated Bonding (TAB) technology. Via holes are formed through a flexible insulating layer, such as polyimide, and are plated through when conductive fingers are formed on one surface of the layer. The resulting structure is then bonded to a semiconductor chip by means of the conductive pads formed on the surface of the insulating layer opposite to the conductive fingers.

Abstract: Disclosed is a method and apparatus for achieving a uniform coating of metal, such as copper, on an insulating strip, such as polyimide. After activating the surface, the strip is passed through a plating cell which includes a pumped solution mixed with a gas to achieve frothing. A high current is supplied to the cathode, so a cooled cathode construction is provided to prevent burning of the strip. Further features of the apparatus include a means for splicing strips, and a cantilever beam cathode contact for improving the physical contact with the strip.

Abstract: Disclosed is a method for forming silver coatings on material, particularly ceramic filter material. The surface is first sensitized by applying thereto a solution comprising a silver ammonia complex and a solution comprising a reducing agent. This forms a thin silver coating which is then silver plated.

Abstract: Disclosed is a method and apparatus for plating metal onto wire or ribbon. The wire or ribbon is wrapped around two or more barrels with grooves formed around the outside surface. The barrel is immersed within an appropriate electroless or electroplating solution, and rotated at a speed depending upon the immersion time needed for a particular desired plated thickness.

Abstract: A chromate conversion coating formed on an article in an acidic chromating bath in reaction with a metal surface on the article, such as cadmium or zinc, is stabilized by subjecting the coating to an alkaline bath having a pH in a range between 11 and 12, immediately upon removing the article from the chromating bath and without first rinsing the article in water. The stabilized coating exhibits resistance to damage during rinsing and drying operations.
