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.

Performance Characteristics:
• Minimize micro-solderballs
• Extremely shiny joints
• No streaky, white residues
• Improves soldering performance
• Eliminates the need and expense of cleaning
• Classified as ORL0 per J-STD-004
• Compliant to Bellcore GR-78

Application
959 can be applied to circuit boards by a spray, foam or dip process. Flux deposition should be 120-240 µg of solids/cm2 (750-1500 µg of solids/in2). An air knife after the flux tank is recommended in a foam and wave application to remove excess flux from the circuit board and prevent dripping on the preheated surface.
