Abstract
An electrochemical deposition system includes a cathode and a printhead. The printhead is spaced apart from the cathode, movable relative to the cathode, and comprises a plurality of deposition anodes. The system further comprises a capacitive sensor that includes a first electrically-conductive layer, at a known location relative to the cathode, and a second electrically-conductive layer, at a known location relative to the printhead. The system additionally includes a processor, electrically coupled with the capacitive sensor and configured to determine a distance between the cathode and the printhead in response to a capacitance of the capacitive sensor.
