Looking into possibly receiving samples of polyester masking dots for conformal coating. Our usage of polymide dots have really increased in the past months and we're always looking for a reduction in costs. The only information I've found is that po

In the past, I've used kapton tape for masking, as well as masking tape and solder mask as you've described. I've also used dummy connectors, or connector caps to cover connectors/pins. In the end, though, I'm not sure any of these methods decrea

Yes - the frame is built to nominal per print then the tape pieces are placed into areas in the frame as required. I had the stencil house cut #'s into the frames designating each different size. When I cut the tape pieces, I put them on a large, s

The adhesive type is the problem generally - latex adhesives used are not compatible with the silicone. Humiseal offer silicone compatible tapes & dots although they are quite expensive. I found a 3M product which is compatible with silicone based co

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
