The Sn42In58 indium solder wire features a tin content of 47.5~48.5% and minimal impurities (less than 0.2g). The wire features excellent weldability and oxidation resistance, making ideal for both wave soldering and dip soldering processes. Due to the high purity of the material, it provides outstanding fluidity during the soldering process and is widely used for die-attach applications.
