Product infoKester 186, under MIL-F-14256, was QPL approved as Type RMA. The flux residue after soldering is non-corrosive and non-conductive. 186 rosin flux has been developed for use in critical applications where difficult assemblies are to be soldered, but process requirements stipulate use of Type RMA flux. This flux possess high thermal stability for soldering multi-layer assemblies which may require a high preheat temperature or longer temperature dwell time. 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. Photo of current Kester bottle in use available upon request :)(LOT#, DOM, DOE) Always buy with confidence fromDickie’s Garage Sale 🙂
