Overview
Kester 959T is a no-clean, non-corrosive, halogen
free liquid flux that is designed for the wave soldering
of conventional and surface mount circuit board
assemblies. Kester 959T was developed to
minimize the formation of micro-solderballs during
wave soldering operations. This flux contains a
small percentage of rosin (0.5%), which improves
solderability, heat stability and surface insulation
resistance. Kester 959T offers the best wetting
and the shiniest solder joints of any no-clean,
solvent-based chemistry. Kester 959T leaves
evenly distributed residues for the best cosmetic
appearance.
