At present, the term of pulse plating denotes not only square-pulsed current plating but also various other types of modulated current plating.These various types of pulse plating are categorized electrically, and the gap between pulse plating theory and it's practical application are presented.And it is suggested that the research papers on pulse plating must be studied enough in proposing to bring pulse plating to the practical level.The method to choose more suitable pulse plater to it's purpose is presented, and it is mentioned that the improvement of the equipment for pulse plating including DC wiring increases the effect of pulse plating.
