Solder (or brazing filler metal) serves as a filler metal in the process of brazing. In contemporary manufacturing, welding technology functions as an essential method for uniting electronic components, metal parts, and precise devices. The solder melting temperature has a direct impact on the quality, effectiveness, and suitable situations for welding. From conventional tin-lead alloys to eco-friendly lead-free options, and specialized high-melting-point solders or low-temperature solders, the differences in melting single temperature illustrate a significant interaction among material s ...
