ABSTRACT:
A method and composition for protecting and enhancing the solderability of a metallic surface. A mixture which includes a chosen protective material and a dicarboxylic acid fluxing agent is applied to the metallic surface to form a protective film or coating which also enhances the solderability of the metallic surface. The mixture is applied to the metallic surface as a solution having a solvent carrier which evaporates to leave the film. the film is heat activated at soldering temperatures to release the fluxing agent.
