Title:
COPPER-NICKEL ALLOY ELECTROPLATING DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/059833
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a copper-nickel alloy electroplating device that can stably form a copper and nickel plating film having a homogeneous composition on an object to be plated, and enables use of a plating bath for a long period of time. The present invention provides a copper-nickel alloy electroplating device (1) characterized by comprising: a cathode chamber (4) in which an object (5) to be plated is placed; an anode chamber (6); an anode (7) disposed in the anode chamber; an energizable diaphragm (14) arranged to separate the cathode chamber and the anode chamber; a cathode chamber redox potential adjusting tank (8) for adjusting the redox potential of a plating solution in the cathode chamber; an anode chamber redox potential adjusting tank (10) for adjusting the redox potential of a plating solution in the anode chamber; and a power source unit (36) for passing a current between the object to be plated and the anode.
