发明名称 Method for analyzing additive concentration
摘要 A method for determining the effective quantity of an organic additive in an electroplating bath involving passing an inert electrode through a predetermined sequence of voltammetric steps including a step of plating the electrode at a given applied potential, stripping the plated metal at a given applied potential, and conditioning the inert electrode without applied potential; correlating the quantity of additive with the coulombs utilized during the metal stripping step; and using the same predetermined sequence of voltammetric steps for a bath having an unknown quantity of additive.
