Just to add my two cents,
Gold over copper does work we have some old parts that calls it up. This is
because of the minute effect of nickel on the electromagnetic field around
the parts.
Sometimes nickel is avoided because it has to be.

Subject: [TN] Gold over Copper?!?
I am losing my mind...
I have just been asked to specify a flex circuit to have 3-5u in of gold
directly on the copper. (That's right folks, no nickel!)
This might be okay if a few parts were being soldered in place, but one
end of the flex is for a FPC connector (also gold plated).
Is this a good idea? Your comments, please, please, PLEASE!
Or else I am losing my mind... hey, where did I put my mi...
