A printed circuit is provided that is capable of operating at temperatures above 200.degree. C. A printed wiring board has a plating scheme of Tin plating over sulfamate nickel plated over copper. The materials are electroplated in the pattern of the desired circuit. The copper provides a conductive material for carrying electrical current. The sulfamate nickel is a ductile material that serves as a barrier between the copper and the Tin and is able to maintain its strength under temperatures of...
