Abstract (en)
[origin: WO2011070933A1] Disclosed is a plating solution which does not result in pinholes in a metal film even if the metal film is less than 0.1µm thick. Partial plating is performed using an electrolytic hard gold plating solution containing gold cyanide and/or gold cyanide salt, water-soluble cobalt salt or water-soluble nickel salt, conducting salts of organic acids, an aromatic sulfonic acid compound, a combination of one or more items selected from a group consisting of carboxylic acids, oxycarboxylic acids, and the salts thereof, and a nitrogen-containing five-membered heterocyclic compound. Consequently, pinholes are not caused in a metal film even if the metal film is less than 0.1µm thick.
