We have used many ways of measuring but all are either messy, inconsistent or time consuming. We have done wet, glass slide dry, etc. We are currently using a kapton tape dot system. Spray the board, remove the dot and measure it, subtract the thick

We aware of the extend time for cure, and in the CA activity we tried plasma etch and expose the sample to the current process, a screen test of 4 cycles -50C to 125C and the CC held in place. Std IPC tape test passed in current process and modifie

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

(or just some static-safe foam tape) I need to seal a wire terminal block to a board for conformal coating purposes. Currently we glue it to a shim and glue the shim to the board (yuck), but I want to use die cut gaskets if I can make it cost effec

I've recently been placed in control of operations of our SCS conformal coat sprayer and I must eliminate problems with wicking of humiseal 1b73 into surface mount connectors while also trying to minimize masking as much as possible. We use a 55:45

I'll chime in here as well. If you have adhesion problems, 90% of the time it's contamination on the substrate (soldermask, flux residues, cleaner residues, etc.). Like Dave said, omega meter is a test for gross cleanliness, and it's OK for process

It's a Spectrum Technologies Sienna 300 Series. The main down fall is that you can only program x and y (as far as I know). By that I mean you can't do circles or diagonals. Only squares and rectangles or shapes with only vertical and horizontal s

I'm working on bringing up a new conformal coat process/workcenter and have a few questions I'm hoping someone might have experience with. Right now we're manually spraying both coating materials (1B31 and 1A33 from Humiseal) using HVLP guns. I run

Ashok: You should select and use low residue tapes. But ya know, ya go out and research a great tape and if yer not careful, the buyer will second source ya and (surprise) ya got residues again. We have found that Lemme say this about Katon tape
