The lead free solder wire and solder bar will gradually replace the tin-lead solder, as there is an increasing demand for environmental protection around the world. Most of no-clean and lead-free soldering wires contain the 2% rosin flux.
Based on customer requirements, the lead-free solder wire manufactured by us usually has the lead content of less than 100ppm. This product is commonly used for the soldering of electronic components, computers, copper plates, PCB, and other metal equipment. It is characterized by favorable wetting property, fast soldering speed, outstanding anti-oxidant property, high tensile strength, and much more. Additionally, the tin will not splatter during the soldering process.
The lead-free soldering wire in our company can be categorized into all kinds of alloy solder, such as Sn99%, Sn-Cu, Sn-Ag-Cu, Sn-Ag, Sn-Bi, and more. Some types of alloy solder wires can be made to have the wire diameter of over 0.1mm.
