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
