Abstract
A process control circuit which is adapted for the control and monitoring of a plurality of parameters in one or more metal-depositing baths, has parameter control circuit blocks for each of the parameters to be measured. Each of the parameter control circuit blocks has a measuring stage for producing a measured value corresponding to one of the parameters, a calibration stage for calibrating the measuring stage, a comparison stage for comparing the measured value to a stored nominal value, and a dosing circuit which is connected to the comparator and which doses the metal-depositing bath in response to a comparison signal from the comparator.
