We have a lighting ballast in for failure analysis and arent sure how to get the encapsulant "tar" from it?
This is a lighting ballast and we have the metal covers removed and are left with a ballast assy built on a pcb, and covered in a thick, black, semi-pliable, tar-like encapsulant.
The tar-like encapsualant smells just like roofing tar. If you lay it on a piece of notepaper it stains it just like roofing tar. It can be peeled away just like a roofing tar. We are afraid of poking too much and damaging components or circuits. Anybody have experience with it? - and know what it is? and how to let it soak in a pan of something and rinse this stuff of instead? Better ideas?
Thanks in advance,
