Summary
A description is given of the CEER process which electrochemically regenerates etchants used in printed circuit board (PCB) production by electrolysis in a cell divided into anode and cathode compartments by a semi-permeable membrane. As well as the etchant being maintained in a highly active condition by oxidation the copper etched from the PCBs is recovered by deposition at the cathode. The application of the process to the two most widely used etchants is described in detail and the economics of the CEER process are compared with those of the conventional etching systems. It is shown that the initial higher capital cost of the CEER process is rapidly recovered by the savings produced by its operation.
