1) Viscosity measurement of the coating prior to spray, spraying and charting metal coupons for sprayed and cured thickness of the coating at various points of the conformal coat run 2) Yes, manual inspection 3) No, it wasn't able to inspect with t

When conformal coating a PCB, when it comes to components such as alum caps, if no keep-out specified for SMT, would you recommend coating the entire component, or would you only coat the bottom portion (where conductors/leads are present) Moreover,

I had send my coating board to the test lab for adhesion coating test. 3 times send, the result 3times fail. The coating chemical use is Humiseal 1B31. The process is clean the boards at washing process use the Vigon A200 saponifier mix with DI wate

| | | Has anyone out there tried to parylene coat plastic parts prior to soldering them to a pcb? I'm looking at several potential applications where fewer than 5% of my components on a pcb are plastic, yet from a reliability aspect (environmental co

Hi, I am running a circuit board that needs a part to be put on it after cleaning and before conformal coating. the only problem is that after cleaning and hand assembly of the part, there is a thin whitish residue in the ckt board that one can see w

We know nothing of DeFelsko, but do understand how they distinguish between the solder mask and the conformal coat. DeFelsko manufactures hand-held, non-destructive coating thickness gages that are ideal for measuring the dry film thickness of confo

We use Dow 2620 silicone conformal coat applied with PVA1000 sprayer machine. If used on a daily bases, we have no problem. If we let the machine sit idle for over a week, we will get bubbles in the conformal coating. Sometimes, purging the line w

this is one of my project. I have tried to remove coating only on those areas with alcohol and thinner, then program the machine to coat the removed area again. But the result obviously shows that two different tones of coating on the board. I also
