The next question how do you do repair through conformal coating . Opps! Better off having done all your inspection and testing first! Hopefully your question is for service! regards sarason

You can inspect joints using an X-ray machine and we use a sand-blaster type machine which blasts (Starch) to remove the conformal coating. (Carbo Blast). However; the inspection should be done prior to Coating, as we all know some jobs are rushed t

What can cause solder balls to appear after conformal coating? Using Dymax 9-20557, light curing for 1.5 mins. Can too much heat from light cure cause solder balls?

I've been involved with no-clean flux and conformal coat in the past.It has been my experience that the amount of no-clean flux used is proportionate to how well the conformal coat adheres to the boards.No clean paste did not affect adhesion. The co

While there may not be any specific requirement to cleaning prior to coating, cleaning an assembly prior to coating will only serve to increase the reliability and integrity of the coating. Some residues from low-solids fluxes can interact with conf

You might want to check int using a BGA underfill material prior to coating.

Does anyone have any input on the need to bake out an assembly prior to the conformal coat process? I understand baking out components/pwb's prior to processing through the reflow or wave solder process if the material shows excess moisture absorbtio
