I know Micro Care made a unit that removed conformal coating with compressed air and a solvent. But they no longer make it. Does anyone have the 2000 version of this unit and may want to sell it or know of another compressed air solvent solution, p

Water soluble process, yes. The machine is old and fixed at 4 ft/min by someone way before me. Looking into ways to reverse that to allow for adjusting the conveyor. Trying to determine how the contamination gets onto the boards. So far testing has i

I'm using urethane conformal coat and have fisheyes and dewetting after coating even though the PWAs have been through the wash cycle twice. I'm looking at using Ionox 13302 in an ultrasonic cleaner as a short term solution until root cause can be id

Hi! We have both Dip & Spray conformal coating processes & have never done any kind of baking before the process! I am assuming the reason for baking would be the same - ie, remove any moisture on the brds since moisture will create failure of the co

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

We are looking for advice on removal of BGA components once urethane conformal coating has been applied and cured.

There are many possibilities: * Conformal coat is incompatible with surface residue on the board * Conformal coat is incompatible with solder mask on the board * Moisture is out-gassing from the board * Conformal coat is too thick and does not allow
