If you use gold/tin-lead there could be a galvanic reaction which will
cause
corrosion. If the connector is gold plated then I would recommend using a
gold
plated edge connector.

Subject: [TN] Tin>Gold Versus Gold>Gold contacts?
HI there guys,
I wonder if someone could give me some basic metallurgy type advise.
I have laid out a board that has edge connector fingers on one side.
It is to plug into a connector that has some gold plated fingers on it.
I would like the PCB to have gold plating on the edge connectors &
others would like it to
be just HASL coated (as its far cheaper).
The question is... how well do gold plating & tin/lead plating fare?
Is this connection likely to corrode or will they exist in harmony ok.
Also will a very dry atmosphere cause any problems to these connections?
Thanks in advance - Matt
