| titleOfInvention | Metal surface protective agent and treatment method |
| abstract | (57) [Abstract] [Purpose] A chemical conversion rustproof coating, an adhesive chemical conversion coating, which has excellent moisture resistance, heat resistance, and chemical resistance, on the metal surface of printed wiring boards. Chemical resistance chemical conversion film is formed, wettability and spreadability of low melting point cream solder, solderability after reflow, The effect of having good wettability can exert a particularly remarkable effect for surface mounting an electronic component. In addition, the adhesive chemical conversion coating has excellent rust prevention, heat resistance, good adhesion of solder powder, and has the remarkable effect of improving solder spreadability, wettability, and uniformity after reflow treatment. The mounting density of the plate can be improved. [Structure] The method of using the metal surface treating agent of the present invention is A compound represented by (Chemical formula 1) to (Chemical formula 10) and an organic acid, By applying a metal surface protective agent containing an inorganic acid, a metal compound, ion-exchanged water, etc., a chemical conversion film having excellent rust prevention, moisture resistance, heat resistance, chemical resistance, and tackiness is formed. |
