We thought of that and it seems one very logical thing to do. The only
problem is that
the boards are coated at our supplier's plant. And you know how QA persons
are...
how can we prove that the aluminum part was coated at the same time then the
batch
etc...
We have to monitor our supplier and got solid evidences.
Thank you all! If any other idea has not been through yet don't hesitate...
I'm all ears...
or all EYES!

I agree with Brian. We place a 2x3" piece of aluminum plate next to the
assembly during coating, which gets coated at the same time. A part of the
plate is masked with tape so you can measure before and after cure.

Coat a lump of metal at the same time and use that to measure the
thickness.
