【Abstract】 The bath components and the operating conditions for a new electroplating technology of solderable bright Sn-Bi alloy were studied. The covering power and throwing power as well as cathodic current efficiency and depositing velocity of the bath were determined. A uniform ,compact ,bright and excellent solderable coating with good adhesion was obtained by the experimental electroplating.更多还原
