Schematic of the control circuit. 2.Current begins to flow and plating starts 3.A master control circuit (MCC) reads the current value at the first part and compares it to the programmed value. The MCC then sends any required current adjustments to the CCC until the programmed current set point is met. 4.MCC scans to the next part and repeats the same process 5.After the last part is adjusted, the MCC returns to the first part and the cycle repeats. 6.This process continues until the plating cycle is completed.
