Soldering Flux, 952-S, Non-Rosin, Organic, 1 Gallon
The Kester 952-S is a zero-halogen, non-rosin organic flux designed specifically for use in tabber and stringer equipment of the Photovoltaic Assembly (PV) module industry by soldering tabs to cell contacts. 952-S could be applied directly to interconnecting ribbon by hand soldering or auto-equipment with a tabber and stringer soldering system, by dipping or spraying.
Because of the extremely low solids content (around 2%), and the nature of the activator system, virtually no residue is left on the cell after soldering. Cell are dry and cosmetically clean as they exit the tabber and stringer machine. 952-S has a wider operating window varying with the temperature range and can be used in SnPb, SnAgPb and Pb-free alloys. 952-S is classified as ORL0.
