CAIG Rosin Soldering Flux is a general purpose flux for soldering electrical connections. CAIG Rosin Flux is a mildly-activated rosin flux that is considerably more active than water-white rosin. Activity closely approaches that of fully activated rosins. The flux is thermally stable enabling excellent wetting and reduced carbonization at soldering temperatures. This flux conforms to all of the requirements of Type RMA. Likewise, it meets the rosin core, mildly activated of Federal Specification QQ-S-571. CAIG Rosin Soldering Flux meets DOD-STD-2000 & also the IPC-J-004 standard for type ROL0, the lowest residue corrosivity category.
