Abstract
Official abstract text for this publication.
This plating liquid contains (A) a soluble salt that contains at least a stannous salt, (B) an acid selected from organic acids and inorganic acids or a salt thereof, and (C) two kinds of surfactants of an amine-based surfactant (C1) and a nonionic surfactant(s) (C2 and/or C3). The amine-based. surfactant (C1) is a polyoxyethylene alkyl amine represented by general formula (1); and the nonionic surfactant(s) (C2 and/or C3) is a condensation product of a polyoxyethylene and a polyoxypropviene represented by general formula (2) or general formula (3). In formula (1), x is 12-18 and y is 4-12. In formula. (2), m is 15-30 and (n1+n2) is 40-50. In formula. (3), (m1+m2) is 15-30 and n is 40-50.
First claim
Opening claim text (preview).
1 . A plating liquid comprising (A) a soluble salt containing at least a stannous salt, (B) an acid selected from organic acids and inorganic acids or a salt thereof, and (C) an additive, wherein the additive contains two kinds of surfactants of an amine-based surfactant (C1) and a nonionic surfactant(s) (C2 and/or C3), the amine-based surfactant (C1) is a polyoxyethylene alkylamine represented by the following general formula (1), and the nonionic surfactant (C2 or C3) is a condensation product of a polyoxyethylene and a polyoxypropylene represented by the following general formula (2) or general formula (3). wherein, in the formula (1), x is 12 to 18 and y is 4 to 12. wherein, in the formula (2), m is 15 to 30 and n1+n2 is 40 to 50. wherein, in the formula (3), ml+m2 is 15 to 30 and n is 40 to 50. 2 . The plating liquid according to claim 1 , wherein the additive further comprises two or more other additives among a surfactant other than the two kinds of the surfactants (C1, C2 and/or C3), a complexing agent, a glossing agent and an antioxidant.
