Abstract: In accordance with the invention, a metal substrate (10) is coated with a multilayer surface finish (11) comprising, in succession, an amorphous metal underlayer (12) a corrosion-resistent metal middle layer (13) and one or more outer layers of precious metal (14). In an exemplary embodiment the metal substrate comprises copper alloy, the amorphous metal underlayer is Ni-P, the middle layer is nickel and the outer layer is palladium. The resulting structure is particularly useful as an electrical connector.

Abstract: The present invention is directed to a lead frame in which the metal lead frame substrate is copper, copper alloy, or nickel alloy. The lead frame substrate is coated with a conformable nickel coating that is crack-resistant when the lead frame is bent to an angle of at least 82 degrees with a bend radius of about 150 mu m to about 300 mu m. Bending the lead frame in this manner causes surface deformations in the lead frame substrate. Cracks do not appear through the thickness of the conformable nickel coating of the present invention when the depth of the deformations that result from this bending do not exceed about 5 mu m.

Abstract: A process for producing sodium gold sulfite in solution is described. The sodium gold sulfite solution is useful in gold electroplating baths, and can be used in applications which require pure, soft gold deposits. A process is also described whereby the sodium gold sulfite solution can be solidified by a freeze-drying process.

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.
