Sn99.3Cu0.7 Lead Free Solder Wire
PAI Sn99.3Cu0.7 RoHS compliance solder wires are being formulated with virgin raw metals processed in state-of-the-art Vaccualloy Technology that brings world class quality along. Here, oxygen interaction with alloy is nil and thus, dross formulation is reduced at PCB assembly process. Also an increased flow rate & reduced impurities found. PAI Sn99.3Cu0.7 alloy is compatible for a typical range of flux application formulas used in Electronics Industry today.
