Manual/Spec Sheet

Product Description:
Kester 951 is a halogen-free, non-rosin organic Flux Pen® that is specifically designed for rework of conventional and surface mount circuit board
assemblies. The extremely low solids content (2.0%) and nature of the activator system results in practically NO RESIDUE left on the assembly
after soldering. There are no residues to interfere with electrical testing. Kester 951 exhibits improved soldering performance to minimize solder bridges (shorts) during rework operations. This flux is suitable for automotive, computer, telecommunications and other applications where reliability considerations are critical. The surface insulation resistance on soldered boards is higher than that provided by typical organic water-soluble
fluxes. Kester 951 contains a corrosion inhibitor such that no corrosion products are formed when bare copper surfaces are exposed to humid environments.

Performance Characteristics:
Improves soldering performance
Eliminates the need and expense of cleaning
Non-corrosive tack-free residues
Classified as ORL0 per J-STD-004
Compliant to Bellcore GR-78
