performance:
Due to the relatively low cost of tin-lead solder bars, our company advocates the most cost-effective concept and produces tin-lead solder bars with various alloy compositions and functions. We have electrolytic solder bars, high-temperature tin bars and all-in-one series of tin-lead solder bars. In particular, 63/37 solder bars have various advantages that lead-free solder bars cannot match, and they are recognized as the best tin-lead solder. It is loved by the electronics industry for its good soldering performance. It is widely used in automatic wave soldering and manual soldering operations. The 63/37 solder bars produced by our company have the advantages of good fluidity, wettability, and solder joints. Bright; excellent antioxidant, low tin dross; the addition of additives can change the crystal structure of solder joints, reduce internal stress, and resist the growth of whiskers; excellent joint performance, very few sharpening and bridging; solder joint machinery Good performance. (Shape: casting bar, extruded bar)
