You can use electroless nickel/palladium/gold for gold wire bonding. It is as good as electrolytic soft gold over electrolytic nickel.

Not sure how you'll accomplish this Steve.... Electroless nickel is applied to an etched pattern, thereby removing the electrical connections that you'd need for the gold electro-plating process. Unless you're "bussing" everything together, that is.

Gold wire bonding – we normally plate electroplated soft gold over electroplated nickel. Will electroplated soft gold plated on top of electroless nickel work as well. Thanks. Steve Kelly
