NC277 VOC-Free Liquid Flux

Passes IPC SIR-004B
Low Post-Process Residue
Broad Process Window
Excellent in Extended Dwell Time


NC277 Liquid Flux is a water-based VOC-Free flux that has performance and reliability characteristics equal or superior to many alcohol-based fluxes. A medium-solids/residue flux, NC277 has an exceptionally durable and powerful activator system making it ideally suited for high thermal mass assemblies such as backplanes, power management, servers and palletized assemblies. NC277 can be used with all common lead-free wave soldering alloys including tin-silver-copper, tinsilver, tin-copper, and others. NC277 has proven to reduce preventative maintenance requirements for spray fluxing applications and will not damage soldering equipment or most painted surfaces. While designed to be a no-clean, any remaining NC277 residue can be cleaned if critical to the product application.
