ABSTRACT:
Thin layers of aluminum (13) and palladium (12) are deposited and annealed to produce aluminum-palladium alloy (14). The surface of the alloy (14) is exposed and treated with an aluminum etchant to produce a catalytic surface (15). The catalytic surface is used for electroless plating of nickel, providing excellent plating uniformity and adhesion, as well as a reduced plating induction time. Several variants of the basic method are possible.
