We clean our PWB assemblies prior to conformal coating by submersing in a
solution of 75% N-PROPANOL and 25% DI water at 125 degrees F for 2 hours.
Never had an Ionograph failure.

        Subject:        [TN] Soaking Circuit Boards in Alcohol

        Hi,
        I happened to observe somebody soaking some assembled boards in
isopropyl
        alcohol to clean them. I was wondering if this was an acceptable
method for
        cleaning. I know using alcohol to clean is okay but, I'm not so sure
about
        actually soaking the whole assembly in an alcohol bath. Any Insight
would be
        appreciated. Thanks.

        Joe
