Lead-free 30g welding wire

Lead-free 30g welding wire,The solder joint is bright and full, there will be no undesirable phenomena such as virtual soldering and false soldering, the melting point is low, the corrosion is small, the welding speed is fast, the thermal shock to the components is reduced, and the insulation resistance is high and there is little residue，Less residue after welding, high insulation resistance，The electrical energy is excellent, the insulation resistance is high, and there is little residue,Less residue after welding, high insulation resistance，Excellent electrical energy, environmentally friendly and fresh, less smoke，The smell is fresh, environmentally friendly, pollution-free, and has no pungent odor (1) The solder joints are smooth, effective, and have excellent anti-oxidation electrical properties, (2) the sufficiency of the national standard does not steal a small amount of neat coiling, (3) the smell is fresh and there is no pungent odor, (4) the residue after no-cleaning and soldering, (5) the quality assurance is made of high-purity tin ingots, and (6) it is easy to use and solder-free, and the melting point is low
