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.

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 900-1000
Knoop.
