A Study of Bright Sn Electroplating Technology in Methanesulfonic Acid System

Abstract:

A bright tin coating was prepared by electrodeposition method in the electroplating system of methanesulfonic acid. The effects of methylsulfonic acid concentration, main salt concentration, current density and brightener on brightness of coating were investigated by orthogonal experiment. A plating process of bright tin was confirmed: concentration of methylsulfonic acid: concentration of Sn2+: current density: 2.5A/dm2, dosage of brightener: at the same time, current efficiency, throwing power, covering power and electrochemical behavior for the process were inspected systematically. And the coatings are characterized by X-ray diffraction analysis (XRD) and scanning electron microscope (SEM).
