The gold is likely to be impervious. The substrate nickel, though,
will be etched by nitric. If it is a pattern plate Ni/Au (Ni/Au etch
resist) then don't put through nitric strip.

Address,
Is hard/soft gold impervious to a Nitric Acid Strip, if so, how many
passes are typically allowed (assuming a gold tab area)?
