So,...
During assembly, say that you see SAC solder wicking up the pins of a
finepitch surface mount header onto the contact area which is
gold-plated.  The gold-plated header normally mates with gold socket
connector.  
What would be the reliability issues with SAC solder in contact with the
gold socket?  Does the silver in the solder mitigate any of the
tin-to-gold issues I have been reading about?
