FLUX FOR FLUX-CORED SOLDER, AND FLUX-CORED SOLDER

摘要

To provide flux for flux cored solder that allows flux residue to have flexibility and can be used without depending on any soldering method. The flux for flux cored solder contains rosin, high molecular compound that prevents melt viscosity of the flux from being increased and allows a flux residue to have flexibility after heating by soldering, and halide that prevents the melt viscosity of the flux from being increased and by a combination of the high molecular compound that allows the flux residue to have flexibility after the heating by the soldering, allows the flux to cover a surface of solder melted during the heating by the soldering.
