Hello,

Apart from the Phosphor Bronze, this sounds like an appropriate finish for
card edge fingers.
The Nickel providing a hard, protective 'anvil' and the gold providing a
corrosion resistant, low resistance contact.
Phosphor bronze is usually the springy metal that the mating connector's
contacts are made from. they too would be Ni/Au plated for the same reasons.
It's best to have the same metal surface on the contacts as the fingers.

Phil.
