    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: 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: In accordance with the invention, a metal substrate (10) is coated with a multilayer finish (11) comprising a layer (13) of tin or tin alloy and one or more outer metal layers (14). An optional metal underlayer (12) may be disposed between the substrate and the tin (13). In an exemplary embodiment the metal substrate comprises copper alloy coated with a nickel underlayer, a layer of tin and an outer metal layer of palladium. The resulting structure is particularly useful as an electrical connector or lead frame.
