ALPHA PV-71 is a zero halogen, halide free, low solid no-clean flux specifically designed to meet the demanding requirements of the Photovoltaic industry when higher pull strength is deemed necessary. This flux is designed such that it limits flux deposits inside tabbing and stringing equipment and spray nozzles, with practically zero residue after soldering. ALPHA PV-71 is a low solids formula employing a unique proprietary activator system which provides excellent soldering in standard module assembly processes & methods that are widely used (preheat and soldering)
ALPHA PV-71 is an alcohol based, low residue formulation delivering reliability in both Pb-free and SnPb applications. Additionally, it also provides excellent solder joint cosmetics with practically no residues left after soldering

Kester 952S is a halogen-free, non rosin organic flux designed for wave soldering conventional and surface mount circuit board assemblies. The extremely low solid content (2%) and nature of activator system results in practically NO RESIDUES 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 and the expense of cleaning is eliminated.

Kester 952S exhibits improved soldering performance to minimize soldering bridges (shorts) and excessive solder defects. This non-corrosive and non conductive flux meets the strictest requirements of Bellcore TR-TSY-000078 specification. This flux is suitable for automotive, computer, telecommunications and photovoltaic applications where reliability considerations are critical. The surface insulation resistance on soldered boards is higher than that provided by typical organic water-soluble fluxes.
