  • Nickel-gold plating copper PCB traces

    Copper on a trace surface oxidizes, resulting in increased contact resistance (copper migrating into the gold can cause the gold to tarnish and corrode). This can be minimized by plating a barrier layer between the copper and gold. Nickel is commonly used as a barrier layer to prevent the gold migrating into the copper on the tracks.

    Electroforming is traditionally done with copper and then plated later with other metals. For practical reasons it would be massively expensive to electroform in pure gold or silver but it is possible. Also, gold and silver are relatively soft so it would take a lot of precious metal to form a strong layer over an object.
