Hi Borch,
I assume you are asking about ENIG.
IPC-4552 Specification for Electroless Nickel/Immersion Gold (ENIG) Plating for Printed Circuit Boards recommends the use of XRF for this thickness measurement. I did not find a specific recommendation as to the preferred measurement location on the ENIG coated surface.
Best regards,
Dave
