Rosin-Core Solder is specifically designed for soldering components where flux residue cannot be removed, making it an ideal choice for electric circuit boards and electrical connections. Containing a mild flux, this solder wire leaves a non-corrosive rosin flux residue, eliminating the need for post-solder cleaning. However, due to its mild nature, the Rosin-Core Solder Wire is best suited for use with copper and brass materials.
