ABSTRACT:
A method and apparatus for analyzing plating solutions. The apparatus generally includes a plating cell, a reference electrolyte input, one or more external additive pumps, and a process controller. In one embodiment, the plating cell includes a cavity therein having a larger volumetric portion adjacent a smaller volumetric portion adapted to hold one or more solutions therein. The plating cell also includes a base disposed adjacent the bottom of the plating cell and adapted to receive and mix one or more test solutions as part of the plating solution analysis. In one configuration, the base includes electrical ports adapted to connect stimulation signals to a working electrode, counter electrode, and reference electrode disposed within the cell. The base also includes a thermal sensor in thermal contact with test solutions contained within the vessel.
