Abstract

An electroplating test cell is disclosed which permits the measurement of the throwing power of an acid. The cell comprises a cathode having a member which is surrounded by an insulating tube. The tube redirects the current in the cell, thereby reducing the amount of metal deposited on the cathode. The pattern of metal deposition on the cathode can be used to estimate the throwing power of the acid in the electrolyte.
