Abstract: PROBLEM TO BE SOLVED: To provide a method for depositing a synthetic plating layer containing a noble metal having wear resistant grains and, to provide an electroplated surface finish having wear resistant grains as the one for an electric connector particularly having high reliability as for an article obtained as the result. SOLUTION: In an electric connector having a connector contact, the contact has a metal base and a surface finish layer formed on the metal base, and the surface finish layer has an electroplated synthetic having a composition of a noble metal in which wear resistant grains have been diffused.

Abstract: PROBLEM TO BE SOLVED: To provide a palladium electroplating method free from the problems of the conventional method. SOLUTION: This electroplating bath includes a metal-sulfonic acid complex (where the metal is a noble metal) and free sulfonic acid. This noble metal includes Pd, Au, rigid Au (containing Ni or Co as a hardener), Pt, Rh, Ru and Ag and their alloys.

Abstract: PROBLEM TO BE SOLVED: To obtain a replenishing agent for electroplating bath, which is low in corrosive properties by distillating a palladium nitrate solution formed from palladium and an excess amount of a nitrate solution at a specified temp. and then adding palladium sulfate and ammonium hydroxide. SOLUTION: A palladium nitrate solution is prepared by washing a prescribed amount of metal palladium with HCl of about 40 to 60 deg.C to activate the palladium and bringing the palladium into contact with an excess amount of a nitrate solution. The nitrate solution is prepared using nitric acid and the nitrate solution is used preferably in the range of about 15 to 50 g/l. The palladium nitrate solution is distilled at a low temp. of

Abstract: An electrical connector comprises connector contacts having a metal base and a surface finish layer over the base, the surface finish layer being a composite of an electroplated precious metal composition and wear resistant particles dispersed therein. In the preferred embodiment, the precious metal layer is a PdCo alloy and the wear resistant particles are sub-micron sized lubricating particles, e.g. polytetrafluoroethylene particles and a flash coat of gold is provided over the composite layer.

Abstract: The specification describes novel rhodium sulfate complex solutions which ha ve a minimum of metal to metal complexing and are mostly complexed through the sulfate groups. Use of these solutions as electrolytes for plating rhodium results in electroplated layers with improved brightness and reduced stress.
