Hi Jim! One test which we have found to be useful is the RTCA/DO-160D
Humidity test. The test is essentially a 10 day test utilizing a cyclic
temperature/humidity recipe. Good Luck.

Subject: [TN] Conformal Coating Process
Happy Monday, Technet:
I'm trying to qualify a new cleaning process for electrical assemblies
prior
to conformal coating (Military boards). The old MIL Specs had as
cleanliness requirement of 2 meg-ohms minimum, is this all I need to do,
verify cleanliness to 2 meg-ohms? What about subjecting the assemblies to
10-day elevated temp/humidity (steady state)? Any recommendations?
