With the right no clean applied below a critical level, I haven't had a
problem with other acrylics.

In testing new no cleans, I found some are incompatable, but most are fine,
as long as the spray fluxer is below a certain level. The critical level is
more flux than required for good soldering.

     Has anyone had experience with conformal coating over a "no-clean"
     flux residue?   Right now we are using a Humiseal - 1B73 Acrylic,
     and using a water soluble flux.  We are in the process of going
     outside with this assembly and most of the contract houses that we
     have talked with use no clean.    thanks
