Balver Zinn solder wire LF3237
BALVER ZINN SOLDER WIRE LF3237 is a high activated water soluble flux formulation for special applications. BALVER ZINN SOLDER WIRE LF3237 shows fast and excellent wetting properties even on difficult surfaces. Because of the high halide content of 1.2 % LF3237 performs very well on all available PCB finishes. The residues must be removed after soldering. BALVER ZINN LF3237 is available in diameters from 0.3 to 3.5 and a standard flux content of 2.2 %. Standard lead free alloys are SN100C, SN97C and SN96C. Lead containing and special alloys are available on request For additional information please refer to the product data sheet.
