Mr. Evtimov, Koh Young and Parmi have this option in their SPC software. You can also choose either Volume, Area, position, height (both in um or %). Here is a screenshot from Parmi. Unfortunatelly i cant find my old Koh Young screenshots. Parmi has

What is the best/most economical way to check the thickness of conformal coating after being processed. Would a standard height gage do? Thanks in advance...

Like other things, the more you pay, the better the gage. I'm not sure which Cyberoptics unit you're considering, but LSM has a lousy gage [R&R ~25%]. We use a microscope with lousy gage that costs waaay less than some laser guided thing. Search t

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

A wet film gage works best.

Russ maybe talking about ASC [ http://www.ascinternational.com/ ]. They can wack the gage on a LSM by about 2/3. That gets it into a range that it's no longer like throwing mud at the wall.

Its nearly impossibile to get any Gage R&R on systems that require the operator to posisition the board to be measured. For this you need an automatic measurement system. There are many vendors out there in addition to CyberOptics, models SE 200 and

| I am looking for information on any Gage R&R studies for the CyberOptics LSM solder paste inspection system. If you are a current user of one of these systems, are you finding any problems with the repeatability due to operator variation? What is

There's a ton of em'. We used the one from Paul N. Gardner Company, part # WF-CCD. They cost 0.95 each, so if someone decides the gage looks better in their garage, it's not that big of a deal. We set up a program that puts down 4 stokes on a test
