ABSTRACT:
Apparatus for maintaining the concentration of components of a plating solution substantially constant during use of a plating bath. The apparatus comprises a sensor suspended in the plating bath responsive to the concentration of one or more plating components of the plating solution. The sensor is capable of generating a signal whereby replenished solution is pumped to the solution to replace depleted components.
