Patent ID: 7238265

Claim:
A fountain-type electroplating apparatus with functions of voltage detection and flow rectification, comprising: an electroplating tank having a shell, a substrate cathode electrode arranged on top of the shell, a circumference of the substrate electrode having a plurality of joints, and a mesh shaped anode arranged at the bottom of the shell, a circumference of the mesh shaped anode having a plurality of joints; a switcher having a first switching point and a corresponding second switching point, the switcher alternately operating with either a positive electrode or a negative electrode; a plurality of connecting line, each of which having one end connected to one of the joints of the mesh shaped anode, and all of each having another ends connected jointly to a node and to both the positive electrode and the first switching point; a plurality of detection circuits, wherein, the first end of one of the detection circuit is connected to the corresponding second switching point, and the first ends of the other of the detection circuits are connected jointly to a node and to both the negative electrode and the second switching point, all the second ends of the detection circuits are respectively connected to the joints of the substrate; a rectification device having a hull, a separating plate arranged under the mesh shaped anode and a pipe connecting to the hull for transporting an electrolyte therein, the separating plate having at least a hole and being connected to and arranged inside the hull; and an overflow tank having an exit hole arranged at the bottom thereof; wherein the electroplating tank is positioned inside the overflow tank, and the rectification device is arranged under the electroplating tank.
