Ken:  How 'bout ...

Finger connector contact area, if applicable, shall be plated with gold over low stress
nickel.  Gold plating shall be a minimum of 20 uinch thick having minimum 99.7% purity.
Nickel plating shall be a minimum of 100 uinch thick.  There shall be no exposed copper at the
finger area.  Plating shall pass IPC TM-650 Test Method - 2.4.1D, Adhesion, Tape Testing.

Why do you put gold on contact fingers?  Is it to prevent fretting corrosion?
