For high temperature (>100 deg C) use gold over nickel. The nickel stops
copper migration. For low currents use gold, there's nothing better. It's
needed on both the terminals and the board. Tin on either makes gold
useless.  For high voltage, use nickel - it's cheaper. If you have deep
pockets (military), contact Ney Company about precious metal terminals
