| titleOfInvention | Electroless tin plating bath |
| abstract | An electroless tin plating bath based on an organic sulfonic acid, a soluble stannous salt and thioureas prevents the tin film from being abnormally grained or excessively precipitated. An organic sulfonic acid containing an anion portion of an organic sulfonic acid having a hydroxyl group in a molecule and not containing an anion portion of an alkanesulfonic acid as an organic sulfonic acid is an aromatic sulfonic acid in terms of anion. A mixture having a molar ratio of oxysulfonic acid / alkanolsulfonic acid = 0 to 0.44, in which hypophosphorous acid is contained in a bath, and a molar ratio of soluble stannous salt (Sn 2+ ) to hypophosphorous acid. Is Sn 2+ / hypophosphorous acid = 0.21 or more. In order to make the plating bath contain no alkanesulfonic acid and contain alkanolsulfonic acid or an aromatic oxysulfonic acid together with the alkanolsulfonic acid, and to adjust the molar ratio of hypophosphorous acid and Sn2 + to a predetermined molar ratio. In addition, the occurrence of abnormal particles and excessive precipitation of the tin film can be prevented. [Selection diagram] None |
