ELECTROLYTIC TIN OR TIN ALLOY PLATING BATH AND ELECTRONIC COMPONENT HAVING ELECTRODEPOSITION ARTICLE THAT IS FORMED WITH USE OF SAID PLATING BATH

摘要

An alkylene oxide adduct of an aliphatic monoamine or polyamine in which a plurality of oxyalkylene chains are bonded to a nitrogen atom in an amine structure in the molecule, glycerin or polyglycerin in which an oxyalkylene chain is bonded to a plurality of oxygen atoms in an alcohol structure in the molecule By forming an electrodeposit using a tin or tin alloy plating bath containing a predetermined branched polyoxyalkylene compound such as an alkylene oxide adduct of Yield can be improved.
