955 Soldering Flux
Kester 955 is a low solid, halide-free, non-rosin organic flux designed specifically for use in tabber and stringer equipment
of Photovoltaic Assembly (PV) through soldering tabs to cell contacts. 955 can be applied directly to interconnecting ribbon by hand soldering and auto-equipment with tabbing and stringing soldering system. It can be applied by dipping or spraying methods. The extremely low solids content (around 1.5%) and nature of the activator system results in practically no residue left on the cell after soldering. Cells are dry and cosmetically clean as they exit the tabber and stringer machine. 955 has a wide operating window and temperature range. It can be used in SnPb, SnAgPb and Pb-free applications.
