Kester® 951 Liquid Soldering Flux
Halogen-free, rosin-free, no-clean, alcohol-based flux, provides excellent board cosmetics & eliminates solder balling and bridging.
Contact UsProduct Overview
Kester 951 is a halogen-free, rosin-free, low-solids, low-residue, no-clean flux. Its extremely low solids content (2.0%) and unique activator system leave practically no residue on the assembly after soldering. Boards remain dry and cosmetically clean as they exit the wave solder machine, with no residues to interfere with electrical testing.
Kester 951 delivers improved soldering performance, minimizing solder bridges and excessive solder defects. The surface insulation resistance of soldered boards using Kester 951 is higher than that of typical water-soluble fluxes. It also contains a corrosion inhibitor, preventing corrosion products from forming when bare copper surfaces are exposed to humid environments.
