HOT SALE !! Kester 951 Flux Pen Low-Solids No Clean for Solder PV Solar Cell Process



Kester Flux Pen 951
The 951 Is the best Flux on the market for Solar Cell Tabbing. A unique tool for soldering and rework. Allows controlled application of flux, eliminating the mess and hazards of flux bottles. A spring-loaded felt tip dispenses just the right amount of flux while limiting operator exposure to soldering chemicals. The tip's chisel point shape allows work in confined spaces while delivering flux only to specific areas as simply as writing. A spring valve prevents flux inside of pen from drying out.Its a low solid flux that leaves no residue and is designed to work with the higher temperatures required by today's lead free solders. I buy in large quantities and pass the savings to my customers.
Description:
1. Superior fluxing ability
2. Instant wetting
3. For better soldering, the choice of an appropriate Flux is as important as the choice of high purity solder.
4. Flux has to facilitate the flow of solder by reducing the surface tension of parent metal and preventing re-oxidization through blocking the air after promptly removing oxide film from parental metal and covering the surface.
5. Low solids
MSDS
Kester 951 is a halogen-free, non-rosin organic flux designed for wave soldering 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. Boards are dry and cosmetically clean as they exit the wave solder machine. There are no residues to interfere with electrical testing. Kester 951 exhibits improved soldering performance to minimize solder bridges (shorts) and excessive solder defects. 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.

Specifications:
