186 Flux Pen® is specifically designed for leaded and lead-free rework
of conventional and surface mount circuit board assemblies.
186 under MIL-F-14256, was QPL approved as Type RMA. Although the fluxing
ability approaches that of Type RA flux, residues after soldering are
non-corrosive and non-conductive.
186 has been developed for use in critical applications where difficult
assemblies are to be soldered, but process requirements stipulate use of Type
RMA flux.
186 possesses high thermal stability for soldering multi-layer assemblies
which require higher temperatures. Exposure to high preheat temperatures does
not degrade solubility of the residue in normal cleaning solvents. There is no
surface insulation resistance degradation caused by the flux residue. The use of
a minimum of ionic activating agents and the inactive nature of the residue
permits leaving the residue on circuit board assemblies for many applications.
The flux residue is also moisture and fungus resistant.
