What should I pay attention to when buying lead-free tin wire
2019-12-25
Tin wire is a type of solder material, which is mostly used for manual soldering products. At present, most tin wires contain fluxes such as rosin. The use of tin wires can reduce the number of processes and improve the efficiency of soldering operations. Everyone knows that silver-containing lead-free tin wire is expensive, so you must pay attention to selection and discrimination when buying. The quality of counterfeit silver does not match its price, and the performance cannot meet the original design indicators, affecting the quality of electronic products. So what should you pay attention to when buying lead-free tin wire? The following is introduced by the editor of Shenzhen Xinghongtai solder wire manufacturer:
1. Regarding silver-containing lead-free tin wire, whether it is the sample, especially the finished product, should be tested regularly and in batches. The testing items are mainly: silver content and lead content. This silver content is related to the performance and cost of the solder wire. This lead content is related to the EU ROHS standard. If the lead content is too high, it will lead to the danger of the final electronic product exceeding the standard, or use a spectrometer to detect.
2. Silver-containing lead-free tin wire is also composed of many alloy components. Different components have different prices and are also used for different purposes. For example: Sn99Ag0.3Cu0.7, silver-containing lead-free tin wire with 0.3 silver, Sn96.5Ag3.0Cu0.5 with 3.0 silver, or Sn96.5Ag3.5 with 3.5 silver, and so on. These alloys are common alloys containing silver and lead-free tin wires, and their price, performance and use are different. The more silver content, the more expensive the price, and of course the better the properties such as firmness and conductivity.
3. For the returned silver-containing lead-free solder wire, test the comprehensive performance of the solder joint after the welding operation.
Shenzhen Xinghongtai Tin Co., Ltd. is a professional solder wire manufacturer.It has been focusing on the research and development of solder wire for 12 years.It provides solder wire, lead-free solder wire, lead solder wire, solder wire, solder bar and solder wire of different specifications.
