Put a known thickness gage next to your boards to be coated. Then coat it in the same pass as your boards. Measure the "new" thickness of your gage and subtract the difference. That will be your coating thickness. This is assuming your coating your o

Is there an industry standard for compatability between multiple testers? For example, if an assembly fails on one tester, but passes on another? I realize that target is 100%, but with analog testers, this is not going to happen. Personally, I
