| titleOfInvention | Pretreatment method for electroless tin plating and method for preventing abnormal deposition of tin plating film |
| abstract | An object of the present invention is to prevent the occurrence of abnormal particles and excessive precipitation in a tin-based film obtained when immersing a material to be plated in a pretreatment liquid and then performing electroless tin-based plating. A phosphoric acid comprising (A) orthophosphoric acid, metaphosphoric acid, pyrophosphoric acid, polyphosphoric acid, hypophosphorous acid, phosphorous acid or a salt thereof, (B) an aliphatic carboxylic acid, and (C) an organic acid This is a pretreatment method for electroless tin plating in which a pretreatment solution containing sulfonic acid is prepared, and an object to be plated is immersed in the pretreatment solution. The plating object is immersed in a pretreatment solution containing specific phosphoric acids, aliphatic carboxylic acids and organic sulfonic acids in advance, and then electroless tin plating is performed. , Tin-silver alloy, tin-bismuth alloy, and other tin alloy plating films can be effectively prevented from being abnormally deposited.
