Work published in 1995 by the Low Residue Soldering Task Force delt with high
frequency application and low residue cleaned and not cleaned fluxes.
Contact Ron Inman or Jeff Koon (Rayteon). I have also being doing alot of
project work on low residue effects on high frequency circuits.  One
important aspect is to be consistant with process residues and ensure all the
flux carrier is driven off and the activator is properly complexed so as to
no absorb ambient moisture. Minimize rework and heat the area where extra
flux may be used.  I hope this information helps your investigation.
