Solder wire, is it better to use high lead or no lead?

Solder wire, Tin wire  in Chinese, solder wire in English, solder wire is composed of solder alloy and flux. The alloy components can be divided into solder lead alloy, solder copper alloy, solder silver copper alloy, and solder silver copper alloy. By heating, rosin additives will be injected into the middle part of solder alloy. The material of soldering is different, divided into welding aluminum solder wire, welding stainless steel solder wire, nickel plating solder wire, water-soluble solder wire, the process of different welding materials are also different, we are concerned about the solder wire in the practical application is good lead, or no lead is good, today to explain.

First of all, there is a standard in the classification of solder wire in accordance with the European Union ROHS standard, which is divided into lead-containing solder wire and lead-free solder wire, the biggest difference between whether it contains lead, and how much PPM of lead it contains. The current international standard for lead-containing solder wire is: Sn63% Pb37%, that is, we often say 6337 tin wire, which is a very good tin alloy ratio with lead solder wire, in addition to lead solder wire and other proportions of solder wire, because of the low cost, it is used in various welding production processes without EU ROHS requirements. The lead-free solder wire does not mean that there is no lead at all, lead-free refers to the lead content is relatively small, can be ignored as lead-free, the EU ROHS definition standard is Pb<1000PPM is to meet the lead-free requirements, in our Singway solder wire lead content standard will be lower than this 1000PPM, Usually at 300PPM and <100PPMyiw, the current production of solder wire, whether lead solder wire or lead-free solder wire can meet the needs of manual soldering iron soldering process and automatic soldering machine soldering process.

It is recommended that you choose the solder wire or based on whether there are environmental requirements, if there is no environmental requirements from the cost reduction to consider the choice of lead-containing solder wire, welding quickly save costs. However, customers have EU ROHS environmental requirements, we must pay attention to the control of lead content, the lower the lead content, the better, Pb<100PPM solder wire can better meet the lead-free environmental requirements, Singway solder wire production of solder wire, tin bar, solder paste, tin ring products can be strictly in accordance with the EU ROHS standard production, small lead, can provide a variety of solder wire specifications and sizes customized, to provide you with a full range of solder solutions, welcome to contact us.
