Abstract

An electrochemical cell for use in electrochemical processes, such as plating processes, has a first electrode which extends circumferentially about at least a portion of an electrode chamber. The article being treated is the second electrode and is disposed within the chamber. Electrolyte is flowed between the two electrodes. Various construction details of the electrochemical cell are developed which facilitate a plating process. In one embodiment, a supply conduit to the electrode chamber has a swirler.
