Louis,
By chance, did you ever publish such a study? I am working on a section
for the IPC Conformal Coating Handbook on thickness measurement and would
like to be able to use such information.

Re: [TN] Conformal Coating measurment
Jean-Francois, et al, several years ago, I did a repeatability and
reproducibility study of a micrometer, for measurement of conformal
coating thickness. I found it to be an acceptable method for determining
conformance to IPC A-610. For process control, I did attempt to judge.
For anyone who is interested, IPC has a nice test method for measurement
quality:

Associated with it in the test methods page is a spreadsheet calculator
and user guide.

Hi Technetters,
What is the proper method for measuring conformal coating thickness?
Were're using a micrometer but I doubt that the method is reliable. A wet
gauge is not out of the question but we would prefer to measure thickness
once the coating is cured.
Thanks!
