Abstract (en)

A method for depositing a tin-bismuth alloy on a substrate, the method including steps of (1) immersing the substrate and an anode in an electrolyte solution that includes water, a stannous salt, a bismuth salt, and at least one of sulfuric acid and sulfamic acid, the anode including tin and, optionally, bismuth, and (2) passing an electric current between the substrate and the anode to form a deposit on the substrate.
