ABSTRACT:
An electrical apparatus for detecting improper operation in the electrolytic plating or etching of a workpiece. Three connections are made from the electrical detection circuit to the work area at the plating or etching tank, namely to the anode bus bar, the cathode bus bar, and the workpiece being processed. In the detection circuit are two polarity sensing devices, which in conjunction with other electrical and manual switching devices, indicators, timers and alarms can detect incorrect operation of the plating or etching process and notify the operator accordingly. Furthermore, in the case where the operator fails to respond to a warning indicator the apparatus disclosed automatically initiates shutdown of the process in operation. The use of three connections and an appropriately interconnected pair of polarity sensing devices notifies the operator when the electrical polarity at the workpiece is incorrect, when the workpiece is attached to the wrong bus bar, or when the time has elapsed in a short preparatory etch preceeding the plating process.
