NC277 VOC-free liquid flux is said to be as electrically safe as alcohol-based flux and has a medium residue suitable for long thermal demands. Withstands thermal preheats required for palletized selective soldering. Has a broad activation range, and is for use in lead-free wave soldering with tin-silver-copper, tin-silver, tin-copper, and other alloys. Reportedly has low post-process residues and can reduce preventative maintenance requirements in spray fluxing applications. Is no-clean, non-visible residue flux, but can be cleaned. Meets IPC SIR 2.6.3.7 test in an air-dried state. Sealed shelf life of nine months at room temperature.
