Could anyone recommend an esd safe masking tape for conformal coating that does not use a silicone based adhesive? I have looked into 3M's 7419 series and am awaiting samples, curious if there is another brand out there people have used. Thank you

John, In addtion to the cleaning process you may wnat to look at the masking materials you are using as well. Are you using any temporary masking tape? If so, do the dewetted areas coincide? Some of these tapes use a silicone-based adhesive which wi

Try using Kapton Tape or masking tape dots instead of the liquid mask.

Has anyone experienced a problem with conformal coating adhesion to IS-410 boards? We are having problems with one suppliers boards. IS-410 boards from other suppliers are fine and all FR-4 boards that I have looked at are fine. We are using Conap

If I am not mistaken you can buy Spray cans of Conformal Coating. For the small batch in the environment you are describing, that might be the ticket. A bit pricey material wise, but clean up is a cinch. A little masking tape, and spray away!

If you get a response to this, I might have a need to look into something similar. Though, I don't need adhesive..I need something more like kapton or masking dots. I am working on a new job that requires conformal coating, and LEDs that need to be

First of all, do not use kapton tape! It tends to cause a dewetting effect around the tape. A call to Humiseal will explain why. There's not really a blanket answer to your question.... Removing cured liquid mask can often result in a fillet ef

Is there a preferred/efficient method(s)(e.g. tape/masking compounds, boots etc.) for masking off specific areas and/or components on a pwb prior to conformal coating?

Hi BJ, Everyone's favourite answer...it depends! If the volume if large, masking boots will save you both, time and money in the long run. Custom boots are relatively expensive to buy, but they pay themselves over time by savings on masking tape. ma
