Lead-free tin bars are an energy-saving raw material without lead chemicals, also known as low-carbon and environmentally friendly solder wires. They have long been successfully developedSGSThe detection does not cause air pollution. What should be noted when using lead-free solder wire? Then, I, Jia Jinyuan, will reveal the secrets for you. When using lead-free solder wire, it is necessary to be careful not to touch the road surface with your hands. Do not touch the battery charging, including the pen cap, as it is very likely to cause an electric shock accident. Professional technicians should also do their best during the operation process......

How to evaluate lead-free and environmentally friendly solder paste? What is the variation pattern of viscosity during the printing process? Generally, the methods we use to evaluate lead-free solder paste include3This situation can be classified into high temperature, medium temperature and low temperature3There are various types and someLEDSome large-scale enterprises use high-temperature solder paste, while others use low-temperature ones. This can also reduce the costs of enterprises and has some negative benefits for this industry. We can understand that the metallic compressive strength of low-temperature solder paste is insufficient. YesLEDCommodities, especially those with solar cells......
