Abstract
An electrical conductor has a metal substrate. A seal plating layer is provided on and exterior of the metal substrate. A nickel plating layer is provided on and exterior of the seal plating layer. A gold plating layer is provided on and exterior of the nickel plating layer. The seal plating layer is a non-nickel based metal. Optionally, the seal plating layer may be tin based. Optionally, the seal plating layer may create intermetallic interface layers with the nickel plating layer and the metal substrate. Optionally, the electrical conductor may constitute a contact configured for mating with at least one of a printed circuit board or another mating contact.
