Manual soldering common solder 30 70

Usually Solder Wire with flux features eigher and acid core or a rosin core and can be combined with lead-based or Lead-Free Solder Wire.

Flux cored wire is generally used for manual Soldering or rework, and is increasingly used in robotic soldering applications. It contains the flux in the center to facilitate the soldering process and eliminate the need for a separate flux. A variety of flux cores are available including no-clean, water-soluble and halogen-free. Flux-cored wire is also used for soldering processes that do not involve electronics.
