NC-264-5 is a new generation resin-free, halide-free, wave solder flux designed to enhance wetting and prevent bridging during the wave soldering process. Based on the popular 263 series fluxes, NC-264-5 offers the same enhanced activity level, as well as lower surface tension than other flux chemistries. NC-264-5 performs well with bare copper, solder coated and organic coated pwbs, leaving negligible post-process residues that are nonconductive and do not require post-process cleaning. NC-264-5 has a unique chemistry and a wide process window making it a drop in for your computer and control assembly electronics.
