The influence of electric current parameters and ultrasonic oscillations on the microstructure and properties of Sn–Bi electroplating coatings

The coeffect of electrolysis mode and ultrasonic oscillations on microstructure, composition and properties of Sn–Bi coatings is considered. It was found that the use of non-stationary electrolysis and ultrasonic stimulation to optimize the deposition parameters, with which it is possible to avoid the deterioration of solderability while improving sludge quality.
