If the gold fingers are pad types which plug into expansion slot connectors, I have used a titanium guard attached to the wave conveyor over the solder pot, which allows the PCB to connect to the fingers but masks the solder from the gold pads along

I'm with John. Back in the old MIL-2000 days, the pot temperature was 245-275C (475-525F). Now, 240-260C (460-480 F) is more accepted for eutechic (eutechicish) solder. My2� Dave F

| | We have some SMT components with gold plated leads. They're actually LCC led packages. A good solder alloy to use would be Indium / Lead to reduce tin dissolution into the gold and avoid the resultant brittle intermetallic compound. However, a re
