Balver Zinn Solder Wire LF2220NC
BALVER ZINN SOLDER WIRE LF2220 NC has been developed for lead-free rework and touch-up of lead-free circuitry. The well-balanced flux activation system leaves minimal non-corrosive residues. BALVER ZINN SOLDER WIRE LF2220 NC provides fast wetting of critical surfaces to form strong joints. With a higher specific heat requirement than tin-lead solder, 20% more energy is needed to heat the soldering tip to 370°C. BALVER ZINN SOLDER WIRE LF2220 NC is also „no-clean“ and halide-free. The standard flux content is 2.2 % and flux residues may remain on the board without cleaning. BALVER ZINN SOLDER WIRE LF2220 NC is offered in diameters from 0.3mm to 3.5mm and is also available in lead-free alloys SN100C, SN96C and SN97C. Lead-containing wires or special alloys are available on request. SN96C and SN97C are in accordance to J-STD-006B! For additional information please refer to the product data sheet..
