I have a design that requires the PCBA to be potted. However I have a shrouded header on the board that I need access to. Is there a way to cover this header during the potting process and then removed the cover after the potting material has cured

thanks for the post... but are you sure that the type of mask i mentioned is photoimageable and as i understood can be removed from desired places (pads/soldering areas) using uv and developer (which i don't know what material is it). and also the

OSHA regulates eye protection under 29 CFR 1910.132 I've had inspectors confirm that eye protection was ANSI Z87.1 compliant, but have never had anyone question the level of protection provided by side shields.

Protect the board: If solder mask protects the board, the level of protection is limited and inconsistent. If you want protection, you need the be thinking conformal coating. Selective ENIG: I believe the reason solderability protection, except mayb
