ABSTRACT:
An apparatus and method for producing an adjustable constant flow of electrochemical fluid. The apparatus is designed for use in an in-tank electrochemical plating bath sensor. The apparatus and method utilize pumping electrodes placed within an electrode chamber. An electrical potential is applied to the electrodes to produce a gaseous stream which produces vertical movement of the electrochemical fluid through the electrode chamber. The voltage applied to the electrodes is periodically reversed in order to prevent the buildup of metal deposits.
