I have a question regarding a test for flux contamination on conformally
coated boards.

I know all about testing uncoated boards but was wondering if there are any
tests for type UR coated boards?

Does a temperature soak do any good at bringing problems to the surface?

Does baking cause any remaining flux to become conductive?

Does a humidity/temperature soak do any good?

What were looking for is a parallel electrical path that might reduce the
value of a small SMT resistor.

Thanks in advance,

KennyB
