NC263UR is a rosin-free, resin-free, halide-free, no-clean wave solder flux designed to promote enhanced wetting during the wave soldering process. NC263UR has a higher activity level and lower surface tension than other no-clean liquid fluxes. NC263UR performs well with bare copper, solder-coated, and organic coated PWBs, leaving

negligible post-process residues that are non-conductive and do not require post-process cleaning for most applications. NC263UR has a unique chemistry and wide process window, which makes it a drop-in for your wave soldering process.
