I may be mistaken, but I thought that some of the no-clean flux residues
were designed to accept conformal coating.  Perhaps your flux manufacturer
can shed some light...

        Subject:        [TN] Cleaning of No-clean Assemblies

        Folks,

        We've been asked to investigate the pros and cons of performing an
aqueous
        wash of our no-clean assemblies prior to them receiving an acrylic
conformal
        coating.  Our management team wants the product to be absolutely
free from
        any type of contamination.

        Has anyone had any experience with this?  What are the possible
advantages
        and some of the pitfalls we could anticipate?

        Are there any knowledge sources that you might be able to recommend?

        Any assistance would be sincerely appreciated.

        Regards,

        Leland Woodall
