There are many possibilities: * Conformal coat is incompatible with surface residue on the board * Conformal coat is incompatible with solder mask on the board * Moisture is out-gassing from the board * Conformal coat is too thick and does not allow

Is conformal coating necessary for products that are used indoors?

I am having trouble with little air bubbles in my conformal coat. It ranges from a few pin sized bubble to looking like spit. We are using Dow 2620 silicone conformal coat applied with a PVA sprayer machine. The conformal coat comes in bladder bags t

Electrochemical migration under conformal coating: That's possible. Very few conformal coatings are water resistant. So, if you have ionic material on your board, standback. Uncured material under several IC: Materials like yours need moisture fro

We're going to begin conformal coating a few of our assemblies as required by our customer. We're using Kester No clean paste and will use cotton gloves to keep the boards clean while handling. My question is: Do we need to clean the boards prior to

Terry, I've never had to deal with conformal coating but I do know that automotive parts manufacturers do a great deal of CC. These are the people that I would be looking to for your answers. Particularly in regard to long term reliability, extreme c

It's weird that it would be just 0805. When we see this it relates to a single part number and it goes way after a time. We use a Humiseal 1B73. I've emailed you the contact for a person that is very knowledgeable on conformal coatings.

We have PVA 354Bench top conformal coating machine. We are going to procure the Humiseal 1B31 material. Is this material is suitable for this model of machine? Is there any special pecautions to be taken while programming? What are the main problemsd

Good morning Mark, No issues around the masking at this point. The issue seem to be in open areas as well as between clad runs. We are using Humiseal 1A33 Conformal Coat.
