  • Tin or tin alloy electroplating bath, and electronic component having electrodeposit formed thereon using the plating bath
    Patent number: 11939691
    Abstract: An electrodeposit formed by using a tin or tin alloy plating bath containing a prescribed branched polyoxyalkylene compound, such as an alkylene oxide adduct of aliphatic monoamine or polyamine in which a plurality of oxyalkylene chains are bonded to a nitrogen atom of an amine structure in a molecule, or an alkylene oxide adduct of glycerin or polyglycerin in which oxyalkylene chains are respectively bonded to a plurality of oxygen atoms of an alcohol structure in a molecule, suppresses formation defect such as abnormal growth of the electrodeposit. The electrodeposit also improves yield from the viewpoint of quality control.
