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?
