Abstract: An electroplating solution for plating bright tin, lead, or tin-lead alloy solder coatings in high speed electroplating applications. The electroplating solution includes an alkane or alkanol sulfonic acid electrolyte, a non-ionic surfactant, a grain refiner and two brightening agents: an aromatic aldehyde and a carboxylic acid. In one embodiment of the electroplating solution, the sulfonic acid electrolyte is methane sulfonic acid, the non-ionic surfactant is octylphenoxy(10)polyethoxy ethanol, the grain refiner is phenolphthalein, the aromatic aldehyde is chlorobenzaldehyde, and the carboxylic acid is methacrylic acid.

Abstract: An electrolyte bath for plating tin or tin alloy onto metal substrates using a high speed plating process is described. The electrolyte bath contains a stannous alkyl sulfonate and an alkyl sulfonic acid. The bath also contains an organic compound that is the reaction product of polyalkylene glycol and phenolphthalein or derivatives of phenolphthalein.
