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

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 have found that Edding do an aerospace marker, which is water based and does not run with the conformal coating. However, this washes off prior to the coating so it is not much use. Looks like we are just going to have to put some clear tape over

Does anyone have a novel idea on how to protect the flex area during conformal spray coating? Currently using Humiseal T30 on the flex but it has to be removed very carefully to insure coating stays intact on the board.

Check with the coating manufacturer and see if they can offer a solution.

inspect => conformal coat ... and standards are aligned with that philosophy. I can imagine doing a good job inspecting assembly after being coated with particular coating thickness, optical properties, lighting conditions. Ultra-thins are so thin

Well that doesnt sound very promising. What im going to do is make sure these two boards I just coated (with the RTV already cured) will be used in house only. In the future we will do any conformal coating operations before potting with whatever mat

We prefer epoxy.

mccabekev, How are you applying the mark? Can you scribe the board?
