    摘要: Baths and methods for electroplating tin or tin-lead alloys wherein the formation of tetravalent tin and stannic oxide sludge is reduced or prevented. These baths contain a soluble divalent tin compound, a soluble alkyl or alkylol sulfonic acid at least one wetting agent, and a hydroxyl phenyl compound reducing agent. Other compounds may be added to the bath for improving its performance during electroplating.

    摘要: A process and bath for electroplating tin, lead and tin-lead alloys. Improved brightness, solderability and broader current density ranges are achieved by the use in the baths of a soluble alkylene oxide condensate to provide a cloud point of the bath above about 90.degree. F., a soluble bismuth compound, an aromatic aldehyde and acetaldehyde. Tin and lead are supplied to the bath as salts of alkyl or alkylol sulfonic acids with sufficient free alkyl or alkylol sulfonic acid to provide a bath pH of less than 3.
