We've used masking tape and peelable (pink) mask to mask our boards before conformal coating for a long, long time. This is a huge time sink, and increases our lead times (particularly because of the cure time for the pink mask). What are other com

By the time they've reached me/conformal coat they're depaneled (assuming they were panelized at all). Also looked at the tape dot method, but that's a no go as well due to coverage needs.

Not exactly SMT but something I recently did that might save you lots of time and money: Complex high $ assy that has 25+ conformal coat keep out areas - most different shapes. All locations are dimensioned on customers' print. We tried a one piec

I will be starting a conformal coating process soon, I am looking for any pointers on 1) Best method for masking components, tape mask, liqued mask 2) Which is best Spray or Dip? 3) Compatiblity with no clean solder paste (flux residue) I have Mil

Looking into possibly receiving samples of polyester masking dots for conformal coating. Our usage of polymide dots have really increased in the past months and we're always looking for a reduction in costs. The only information I've found is that po

In the past, I've used kapton tape for masking, as well as masking tape and solder mask as you've described. I've also used dummy connectors, or connector caps to cover connectors/pins. In the end, though, I'm not sure any of these methods decrea

I actually bought this tape directly from a disrupter of Saint-Gobain series M797. It was placed on 6" x 9" sheets to have unique conformal coating masking cut outs made. Took some effort to get the process worked out but all is well now.

Yes - the frame is built to nominal per print then the tape pieces are placed into areas in the frame as required. I had the stencil house cut #'s into the frames designating each different size. When I cut the tape pieces, I put them on a large, s

The easy part is to determine which parts should be coated. The harder part is making sure the parts that should not be coated do not get coated. I don't even want to think about the amount of labor and materials I've lost due to conformal coat get
