Lead content has always been a controlled part of lead-free solder wire, and the ultimate goal of industry efforts is to minimize lead content. The emergence of lead-free tin wire has solved a major problem for people in the industry, won the recognition of the world, and has become an important part of China's export products, especially exported to European and American countries. The reason why lead-free solder wire has won so much applause is because it has the following characteristics compared with lead-free solder wire;
1. Easy to tin, good electrical conductivity and thermal conductivity
The main purpose of tinning is to protect the soldered product from corrosion by the external environment. The high-quality lead-free solder wire has a fast tinning speed, which can improve the welding speed and reduce unnecessary waste of time. At the same time, the electrical conductivity and thermal conductivity are high, so it is more suitable for the production and welding of electrical and thermal conductive materials;
2. Higher antioxidant capacity, less waste generation after melting
High oxidation resistance is a major feature of high-quality lead-free solder wire, which enables it to be stored for a longer time and resist more external environmental influences. At the same time, the lead-free solder wire produces less waste when it melts, does not waste raw materials, and is more environmentally friendly. Lead-free solder wire is not only environmentally friendly because it does not contain lead, but also reduces the impact on the environment because less waste is generated;
3. The melted material has good fluidity and is easy to weld
The operator needs to experience the stimulation of strong light during the welding process, so the shorter the welding time is, the better it is for the operator's health. The melted material of the top lead-free solder wire has low viscosity, high fluidity, and easier welding, which can shorten the welding time and reduce the operator's exposure to strong light;
Lead-free solder wire has many features and has many advantages compared with leaded solder wire. It has been recognized by domestic and foreign soldering people. In addition to easy tinning, high electrical conductivity and thermal conductivity, it also has high anti-oxidation ability. Less waste, more environmentally friendly, and at the same time, the melted material has a low viscosity, making it easier to weld.
