961-E Soldering Flux
Kester 961-E is a no-clean, non-conductive, non-corrosive, zero-halogen and rosin-free liquid flux that is specifically designed for the wave soldering of conventional and surface mount circuit board assemblies. Essentially no residue remains after soldering. Boards are dry and cosmetically clean as they exit the wave solder machine, thus posing no interference with electrical testing. 961-E has been developed for bare copper soldering applications. This comprehensive formulation possesses improved wetting characteristics, which continuing to exhibit superior corrosion inhibiting properties and providing a non-tacky residue that is considered non-corrosive and non-conductive by common industry specifications. This non-corrosive and non-conductive flux meets the strictest requirements of Bellcore TR-NWT-000078 and IPC-SF-818 specifications. A major advantage of this flux is the reduced odor associated with the soldering process.
