We've tried this a few times and found that w/normal use that a 
     corrosion product forms that leads to increased 
     resistance/intermittent opens.  We don't allow tinned parts in 
     sockets.

We have instances where tin/lead coated pins are inserted into gold plated 
sockets, etc.  Components even have gold/tin-lead or gold/tin interfaces, 
such as an IC socket with a gold contact with a tin sleeve.  Mil-Std-889B 
indicates gold as being incompatable with tin or tin/lead.  Has anyone 
looked into this issue and is there a potential for corrosion formation and 
associated problems?  Again, I just refereing to mechanical contact ( not 
soldering ).
