Abstract
The concentration of a reducing agent in an electroless bath for plating a first metal is determined from the effect of the reducing agent on the electrodeposition rate of a second metal. For electroless cobalt and nickel baths, a sample of the electroless plating bath is added to an acid copper plating solution and the copper electrodeposition rate is measured by cyclic voltammetric stripping (CVS) analysis. Separate analyses for hypophosphite and dimethylamineborane in baths employing both reducing agents are attained via selective decomposition of the dimethylamineborane in acidic solution.
