ABSTRACT:
Plastic housings for electronic components such as plastic cases for electronic wrist watches and calculators have their interior surfaces coated with a first layer of highly-conductive metal to provide static protection for the electronic circuitry contained in the housing, and a second metal layer overlaying the first layer to provide corrosion resistance for the first metal layer. In a preferred embodiment, the metal layers are formed by unique ion plating techniques.
