Generally, people: assemble => inspect => conformal coat

... and standards are aligned with that philosophy.

I can imagine doing a good job inspecting assembly after being coated with particular coating thickness, optical properties, lighting conditions. Ultra-thins are so thin that can't see them.

Seems like the more that you complicate things, the more that you increase your potential for error. KISMIF

You can inspect joints using an X-ray machine and we use a sand-blaster type machine which blasts (Starch) to remove the conformal coating. (Carbo Blast). However; the inspection should be done prior to Coating, as we all know some jobs are rushed then...
