| I am looking into replacing another business division's Acrylic coating process with our Urethane coating process. Unfortunately, MIL-I-46068 doesn't differentiate AR/UR's performance, and the MFR data sheets don't match up at all (they each spec

Does anyone have any experience with DeFelsko Corporation thickness measuring equipment for conformal coat? I am looking for a quicker more accurate way of checking our coating process.

1) Viscosity measurement of the coating prior to spray, spraying and charting metal coupons for sprayed and cured thickness of the coating at various points of the conformal coat run 2) Yes, manual inspection 3) No, it wasn't able to inspect with t

Guys Does anyone have any bright ideas with regards to masking a PLCC socket with via holes directly below the socket, prior to conformal coating ? We've tryed kapton tape and peelable masks but not with desirable results. Our coating process is a t

Tape test to check adhesion and multiple point thickness test - each board has 5 points per side documented for thickness testing & we measure pre & post coating thickness with an electronic meter. Also temp & humidty are also logged, and alarms go o

Parylene coating is done in vacuum curing chambers. This process drives the material under components and into all nooks and crannies. There is nowhere on the board assembly that can escape from the material! I've only seen Parylene coating process u

Greetings...I have a customer that has an assembly that is conformal coated with Humiseal 1A33. This assembly has some components (resistors and FET's) that heated up during operation and has discolored the conformal coating around their location.

Hi Cecil, We using conformal coating in our manufacturing area, we did use to use Humiseal, others have been Bectron and Peters. We recentalt switched all lacquering to Peters, since it is lead free and it is a lot friendly than Humiseal. To answer
