David, obviously a contact is composed of two parts. Changing the PCB side without changing the connector material can be a disaster. The softer side will wear faster. Then there are possible thermocouple effects with dissimilar materials that can interfere with your instrumentation. Fred Townsend

Re: Rhodium PCB

I remember encountering this problem in 1966 and revisiting again in 1975 when the price of gold skyrocketed. Forgive me if I can't quote exact figures. My notes are long gone. I don't know what 'hard electroplated gold' is. Some sort of alloy I guess. Without compsition the term means nothing to

Rhodium PCB

We’re running into life issues on load boards where the Johnstech socket wears through a layer of 50 um hard electroplated gold. Does anyone have experience with Rhodium electroplating as a long life replacement for gold? The gold is specified for a hardness of 160-200 Knoop and Rhodium is 900
