Kester 959 No-Clean Soldering Flux, 1 gal Bottle, Light Yellow, MFR ID 6300000959

Kester 959 is a no-clean, non-corrosive liquid flux that is designed for the wave soldering of conventional and surface mount circuit board assemblies. 959 was developed to minimize the formation of micro-solderballs during wave soldering operations. This flux contains a small percentage of rosin (1%), which improves solderability, heat stability and surface insulation resistance. 959 offers the best wetting and the shiniest solder joints of any no-clean, solvent-based chemistry. 959 leaves evenly distributed residues for the best cosmetic appearance
