cleaning of no clean flux

Comments are: * Sounds like it's necessary to clean "heareous F381, F352 no clean solder paste" in your application. Consider a paste that may be better suited to your application. * If you're cleaning "low residue flux", consider using an organic acid flux? OA fluxes are much easier and cheaper to clean than low res. * Other RF applications have avoided cleaning of low res fluxes. Flux suppliers say things like: -- This material has been utilized on various assemblies with RF designs without cleaning; however, the compatibility of flux residues on RF assemblies is strongly dependent upon circuitry design. -- Post-process residues may remain on the PCB in RF designs without cleaning. Above 2GHz cleaning maybe required. -- Post-process residues may remain on the PWB in RF designs up to 10 gigahertz without cleaning. Above 10 gigahertz cleaning is recommended.
