| titleOfInvention | Electroless gold plating solution and gold plating method using the same |
| abstract | (57) [Summary] [Object] The present invention relates to an electroless gold plating solution containing no cyanide ion, and performs thick gold plating with good adhesion to a base metal at a solution temperature of 40 to 70 ° C for 2 hours or more. To provide a method. [Constitution] monovalent gold ion, complexing agent for the monovalent gold ion, Sugars as reducing agents, oxycarboxylic acids, polyaldehydes, alkali metal sulfides, triethanolamines, An electroless gold plating solution consisting of an aqueous solution containing any one of salts containing divalent iron ions is used at a pH of 8 to 10 and a liquid temperature of 40 to 70 ° C. [Effect] A thick gold plating film with good adhesion can be obtained by a highly safe electroless plating solution. In addition, it is possible to perform partial thickening gold plating using a plating resist that cannot be used because the liquid temperature is high. |
