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

$100K for a full in-line. We can do conventional spray at 30 to 50% less but you must mask components you don't want to coat. If they are on 1 end only of the board, then dip coat which is the least expensive option starting at around $12K for up to
