Pulse-plating method and apparatus

摘要: The present invention provides a method for plating an object with metal coating, allowing uniform coatings to be applied, even inside cavities in the object. comprises steps of: bringing into contact solution comprising ions; counter electrode said connecting electrical circuit between and electrode; applying constant DC current I1 time period t-, so as provide density A-i on surface of that becomes plated coating; second I2 opposite direction t2 A2 object; third I3 same Ii t3 A3 may repeated until is required profile metal. further relates according described method, apparatus carrying out method. also pulse sequence set instructions
