| titleOfInvention | Method for electrolytic treatment of metal surface |
| abstract | (57) [Summary] (Modified) [Purpose] A chemical conversion rust-preventive coating, an adhesive chemical conversion coating with excellent moisture resistance, heat resistance, and chemical resistance on the metal surface of a printed wiring board. A chemical resistant chemical conversion film is formed to improve the wettability, spreadability of low melting point cream solder, solderability after reflow, and surface mountability of electronic parts. [Structure] A method for treating a surface of a metal, which comprises electrolyzing a metal surface with a cathode or an anode in an aqueous solution containing a compound of the following formula or a derivative thereof by a PR method, an AC method, a DC method, an AC / DC superposition method, or an AC combined method. (However, in the formula, R 1 = hydrogen, alkyl group, phenylalkyl group, allyl group, R 2 = hydrogen, alkyl group, phenylalkyl group, alkylphenyl group, R 3 = hydrogen, sulfonic acid group, alkyl group, halogen atom , N = 0 to 17, x = 0-1. ) |
