Abstract:
     This invention is to increase adhesion of the plating and reduce additional losses incurred in chemical plating process by special treatment such as pretreatment using acid pickling agent contg. hydrofluoric acid and chromic anhydride, thorough washing of porcelain after pickling, wash after sensitization and activation, and pre-plating in soln. contg. nickel sulphate, sodium hypophosphite, and sodium pyrophosphate etc. so that the performance of condenser produced by the present invention reaches the product standards.
