        Hi Kenny - one more bit of information you may want to take a look
at -
        "Connector Contacts: Critical Surfaces", author Robert Mroczkowski
of AMP
        Inc, Advanced Materials & Processes inc. Metal Progress, 12/88,
pages
        49-52. This reference covers the basics very well and talks about
the
        pros/cons of tin. Good Luck.

        Subject:  [TN] Gold and Tin Interconnect




        We have an assembly that uses tin plated pins and sockets for the
        interconnection. We are having trouble getting the pin side in tin
but is
        readily available in gold. My question is "is there any long term
problems
        putting a gold pin in a tin plated socket"?

        For years people have put I/C leads into gold sockets without
problem so it
        seems that this should not be a problem but thought I'd ask for any
real
        life experiences.

        Thanks,
