Kester Solder 951 Flux Pen, Low-Solids No-Clean (83-1000-0951)

Description

951 Flux-Pen Low-Solids No-Clean Flux-Pen
Product Description
Kester 951 Flux-Pen is a halogen-free, non-rosin 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. 951 Flux-Pen 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. 951 Flux-Pen contains a corrosion inhibitor such that no corrosion products are formed when bare copper surfaces are exposed to humid environments.
