Hi Dave, I think your approach is more than some others do as incoming inspection. We just look for - damage of any kind - measure the thickness - measure a critical aperture for the correct size (reduction) - look for smooth walls - do Earls "look

First, some people wait a lifetime for ... ;-) Second, how do you guys measure the stencil aperture clog? What do you think of the Magnaplancil from Fendelaz? It�s a double fyv-blue-green CO2 laser refract-defractometer. ;-) Third, do you really

Are you guys providing adequate board support during glue dispense and placement? I've had this same problem with 0603's that I was able to correct with adequate board support. Also, if you're using a Fuji glue machine, what are your temperature sett

Humiseal probably won't work as most of them are solvent based or require pretty high temp cures. MicroCoat technologies manufacturers UV cure epoxy conformal coating materials that have been used to coat just about anythin (except the green fog) Cal
