ABSTRACT:
Process for electroplating and apparatus therefor characterized by guiding just released bubbles to rise up symmetrically between the substrate plate and each of the anode plates so as to cause stable rising currents; providing a pair of passages outside of the bath so as to receive the bath solution overflowing above the upper edges of the bath wall to be jointed with the respective rising currents near the bath bottom; and preventing the descending and turning currents from disturbing just released bubbles near the joint positions of the descending and rising currents.
