Do you buy in the PCB's from a manufacturer? If so, they may well offer such a service for you. We get quite a few different boards that come with either Kapton tape, or liquid masking already applied.

Hi, Our assembly process involves applying Kapton tape to the back side of our device, a laborious cutting and sticking operation. We are scaling up from "cottage industry" so I'm interested to know if you can buy Kapton shapes on a reel cut to our s

First of all, do not use kapton tape! It tends to cause a dewetting effect around the tape. A call to Humiseal will explain why. There's not really a blanket answer to your question.... Removing cured liquid mask can often result in a fillet ef

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

Does anyone know of a company that cuts kapton masking to desired shape per Gerber Data for conformal coat masking applications? (Preferably Pacific Northwest Region).

Try using Kapton Tape or masking tape dots instead of the liquid mask.

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

I am having coating adhesion problem with flex circuits. The cover plate material is KAPTON or Poly imide. The conformal coating material used is humiseal 2A64. The boards are cleaned, measuring less than 4 microgram Nacl per sq in. against acceptabl

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
