Leaded tin wire Sn63Pb37, a solder alloy containing lead and tin, is commonly used in manual soldering and wave soldering processes. Here is an overview of the main application areas for this alloy:
Soldering of Electronic Components: Sn63Pb37 is a classic solder alloy widely used for manual soldering of electronic components such as resistors, capacitors, and chips on circuit boards. Its low melting point and good flowability make it suitable for small, precision electronic components.
Electronics Manufacturing: In addition to manual soldering, Sn63Pb37 is extensively employed in the wave soldering process, particularly in traditional electronics manufacturing. Wave soldering is a method of batch soldering by immersing electronic components in a molten solder wave.
Aerospace Industry: In some applications where solder joint quality and reliability are critical, such as the aerospace industry, Sn63Pb37 alloy may still be used. However, specific aerospace applications may require the use of more environmentally friendly solder alloys, as Sn63Pb37 contains lead, which is subject to restrictions in certain situations.
Military Applications: Due to its reliability and relatively low cost, Sn63Pb37 alloy continues to find use in certain military applications. However, similar to the aerospace industry, certain military applications are gradually transitioning to lead-free solder alloys.
Laboratory and Research: Sn63Pb37 alloy may also be utilized in some laboratory and research projects, especially in small-scale production requiring manual soldering or wave soldering.
It is important to note that due to environmental and health safety considerations, the global use of lead-containing solder alloys is gradually being restricted. Therefore, some industries and regions are transitioning to lead-free solder alloys, such as the Sn-Ag-Cu series, which is considered more environmentally friendly.
