Barbara,
The only 2 forms of conformal coating I have had any experience with are
Humiseal and a Acrylic Conformal coat that I cannot remember the name of...
The difference is, the Acrylic was rework-able and the Humiseal was
permanent.
Maybe someone else has more they can tell you...
Best regards,

Subject: [TN] Conformal Coating of Assembled Boards
Well, my company now has an application requiring conformal coating on
some small assembled boards. We need to mask off 3 connectors and coat
everything else.
I have some information on a product called Parylene applied by Parylene
Coating Services, Inc. in Katy, Texas.
We did a small lot with a simple spray-on process, but that is not the
way to do production runs, of course.
What would you recommend?
Thanks,
Barbara
