Solder materials are commonly used in the electronics industry. Solder is a general term for metal alloy materials used for filling welds, weld overlays, and braze joints. When we buy solder wire, solder bar, etc., in addition to understanding the solder wire specifications, we also need to understand the tin solder suitable for the product, understand its performance, then what are the basic methods of tin solder selection? Below by Xing Hongtai manufacturers The staff introduced to you:

First, the alloy composition of the tin solder is initially determined according to the reliability requirements of the product to be assembled and the assembly welding method. High-demand products usually require good comprehensive performance of all aspects of solder, low soldering process temperature, avoid or reduce adverse effects on the product, and cost becomes a factor to be considered later.

Then, considering the reliability of the product to be assembled, the performance and cost of the lead-free solder, etc., after the primary selection of tin solder, the performance of the primary lead-free solder should be tested or specified according to international or national standards. The dealers go to the third-party qualification testing institutions for performance testing, such as alloy chemical composition, melting point or liquidus, wettability, mechanical properties, reliability and so on. Once the indicators meet the design requirements, they can begin their applied research.

Comprehensive evaluation of the performance of selected lead-free solder, including performance, price, process suitability, reliability, and equipment, process compatibility, etc., to screen out suitable lead-free solder.

The basic method of tin solder selection above is shared here. The solder can be divided into tin-lead solder, silver solder, copper solder, etc. depending on the composition of the composition.
