The question of the tin content of solder wire is believed to be asked by many industry personnel or purchasers when they consult solder wire. In solder products, the tin content of solder wire ranges from 15% to 99.95%. , So what should the tin content of the solder wire be? Different types of solder wire have different tin content. According to environmental protection standards, solder wire is divided into leaded solder wire and lead-free solder wire. Different standards of tin content are also Different, let's analyze it in detail below:
Solder wire is an indispensable electronic soldering accessory in the electronic industry to connect components and circuit boards. The tin content that everyone is talking about is actually the content of the most important raw material in the synthesis of solder wire. The types of solder wire are leaded solder wire and lead-free solder wire. The main components of leaded solder wire are tin and lead. And flux, etc.; and the main components of lead-free solder wire are tin, copper and flux components, some require good conductivity will add silver. The tin content ratio of lead-free environmentally friendly solder wire is generally above Sn99, and pure tin reaches Sn99.95. Other components such as Cu or Ag and additives are added during production. The production cost of lead-free solder wire is higher than that of lead. Solder is very high.
In the production of leaded solder wire, there are various proportions of tin wire according to the proportion of tin and lead. When 63% tin and 37% lead are fused, the hardness, viscosity, and welding effect of the solder wire are good; the industry quotation competition and cost control reasons also separate many other solder wires with different tin contents. Such as 63% tin/37% lead, 60% tin/40 lead, 55% tin/45% lead, 50% tin/50% lead, 45% tin/55% lead, 40% tin/60% lead, 35% Tin/65% lead, etc. At present, the cost of tin raw materials is getting higher and higher than in previous years. The unstable market and repeated epidemics have been in a state of rising tin prices. Everyone will consider the rate when purchasing solder wire. In terms of price, the higher the tin content, the higher the cost, and the higher the corresponding price. On the contrary, the price of the lower tin content will be lower.
Regarding the tin content of the solder wire, in fact, there will be a standard in the industry. No matter which type of solder wire it is, the ratio of tin and lead in the lead solder wire is strictly tested. , The content standard of tin and lead cannot exceed this standard, and the production process of solder wire is not only composed of tin and lead, but also some other fluxes, etc., the factors that determine the price of solder wire, whether it is good or not, etc. In addition to the main components of solder, the flux also plays a very important role, as well as the difference in the production process of each solder manufacturer and the subtle differences in the process.
