Au surface for gold fingers.

     Darrell Daigle posted a request for info on the effect of solder on a
     gold-plated finger that is to be inserted in a gold socket.

     [Body deleted]

     Where the operating environment can lead to corrosion for any of these
     reasons, the corrective action is to remove the solder and replate the
     gold.

I did not know it was possible to remove solder and replate gold...  There
has been a couple of emergency situations when we would have like to have
this capability, be it for PCB's or components, or other...  Can someone
provide specifics?
