Cyclic Voltammetric Stripping, CVS, is an electrochemical technique that determines the concentration of the organic additives in plating bath solutions. The additives in plating baths control the plating of copper onto printed circuit boards, PCBs. The additive is monitored by its effect on the plating rate of copper onto a rotating electrode.
The CVS method uses voltammetry to plate copper onto the surface of a rotating platinum electrode and
then remove that plated copper. The removal of the copper from the electrode surface gives a peak. The
peak area is used for the determination of the concentration of the additive. CVS analysis of organic
additives is a measurement of the influence of the additive on the copper deposition.
