Agree, Kapton. But that is a brand made by DuPont. If you don't have access to that specific brand. The generic term is polyimide tape.

First, this is the result of bad printer setup. Adjust knife pressure, PCB gap, separation speed, tooling, and stencil cleaning. Pay attention to the coating of contacts pad and height of solder mask of PCB.

Similar issues arose for me in cases where the contact pads of components were located below the solder mask level. Ordering a thinner stencil might potentially solve the problem.

Why ultrasonic cleaning? If the ultrasonics are causing problems then nothing will protect the mic. What about peelable mask?

I had the same thought. We use a peelable mask to protect components during conformal coating. It could potentially give it complete protection with relatively easy removal.

We had sucessful removed the solder mask by laser machine and got good result and quality without damage the copper layer. You may refer to youtube here by https://youtu.be/cQHaE3_fiqw

Based on these pictures, please check Board/Stencil co-planarity. Sometimes there might be a distance/gap between them helping this phenomenon(solder mask might be too thick). Also decreasing print speed, might help to mitigate it. You might be too f

I have considered this solution, but syringe application is very slow and it's hard to control thickness. It's good for partial covering or applying peelable solder mask. We need to coat circular board ca. 10cm in diameter. Takes a while even with sp

Mask Musings. Soldermask (SM) and its functions have changed and evolved over the years. As an ex-solder mask applicator, I can remember screening Colonial High Gloss Epoxy soldermask on boards back in the early 80's, ending up with a thickness that
