Thanks, everyone, for your responses.  It appears XRF is a valid tool for measuring ImAg thickness.

I still have a need to have a few PCB samples analyzed.  I have some PCBs that show ImAg copper-like discoloration after only 1 reflow cycle on the non-populated side.  I would like to confirm what this discoloration is, and investigate / confirm if it is due to ImAg plating thickness or porosity issues.

Offline responses ok.
Thank you.
