Solder Wire is one of the most popular forms of solder that is used in manual soldering such as rework. Not all the solder wires are created equal, different wires are suited to different applications and temperatures. The solder wire can also vary drastically depending on the type of soldering alloys. Its melting point is low so it is easy to melt along with the soldering iron in the manual soldering process.
Depending on the application and soldering temperature, many different types of soldering wires are available.
