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

Conformal coating masking: Electronic equipment manufacturer's use conformal coating processes to protect printed circuit modules from moisture, fumes, rapid temperature changes and other environmental conditions. Typically, pressure sensitive tapes

Interesting, never heard of using wax as a coating mask. Not sure how well the AR coating would hold up to a hot alkaline wash (unless you have experience with it), but that stuff usually starts to flake off/de-wet if you just look at it wrong. I'm

I actually bought this tape directly from a disrupter of Saint-Gobain series M797. It was placed on 6" x 9" sheets to have unique conformal coating masking cut outs made. Took some effort to get the process worked out but all is well now.

What is the minimum solder mask thickness required for Class 3 products. We are insisting fabricator of the pcb shop to use only spray coated solder mask. The SM thickness on the epoxy is about 17 microns, In the center of the tracks are 8 microns an

Are you using masking? Conformal coat will de-wet (no pin holes usually, though) due to masking tape adjacent to affected areas if the tape glue chemistry isn't compatible with the conformal coat.

I ordered few times of prototyping gold plating > pcb from China. How to i differentiate they are > ENIG or Flash gold? Hi,Friend , this is very easy to distinguish the ENIG and gold plating pcb, you can stratch the solder mask off and see the co

Jim, Without knowing your location, I suggest: 1 Send me samples of the components you want to mask - maybe I have something available off the shelf. 2 Call Kinarney Rubber Company in New Jersey (sorry, Noo Joysy!) They have a wide range
