NC277 Liquid Flux is a VOC-Free flux that is as electrically safe as an alcohol-based flux and has a medium residue that is suitable for long thermal demands. A medium-solids flux, NC277 is designed for large server boards that may be palletized to achieve top side fillet formation. NC277 can withstand the high thermal preheats required for palletized selective soldering. NC277 provides a broad activation range, proving to be an excellent flux for a variety of process parameters and applications, including lead-free wave soldering with tin-silver-copper, tin-silver, tin-copper, and other alloys. NC277 also passes IPC 18.104.22.168 SIR in an air-dried state. NC277 offers low post-process residues and has proven to reduce preventative maintenance requirements for spray fluxing applications. While designed to be a no-clean, non-visible residue flux, NC277 can be cleaned if critical to the product application.
