We are investigating a similar situation with the exception that the
connection is maintained inside a hermetic (non-oxygen, little moisture)
enclosure. Current testing (>8 weeks temperature cycling) shows that no
significant change in the connection resistance has occured. I don't know the
voltage or the connector resistance level at which problems begin to develop
in this circuit.

Subject: assy:compatability gold vs tin/lead
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 ).
Thanks,
