ANX3133 is an excellent flux with ultra low percentage of solid content. It is suitable for solar application by applying on solar (PV) cell bus strips prior to soldering tab ribbons in place. ANX3133 solder flux facilitates solder wetting by dissolving the oxides present on the surface of the tabbing ribbon as well as the silver metallization bonding stripes on the top and bottom of the solar cell. Rosin residue is non-corrosive, non-conductive, moisture resistant, and fungus resistant.
