Abstract

The present invention relates to a positive electrophoresis coating method and a complete set of equipment when a positive electrophoresis coating is used in image transferring of printed boards; the present invention adopts anode and cathode electrophoresis processes, and comprises the concrete steps as follow: (1) an anode or a cathode system can be achieved by connecting a printed board and a conductive device; the conductive device is connected with the anode or cathode of the electrophoresis power; the anode or cathode of the conductive device is connected with the anode or cathode of power to achieve a anode or a cathode system; (2) the printed board is positioned in the electrophoretic tank filled with electrophoretic painting solution to be conducted electrophoresis; (3) having treated by posing, developing and etching, the positive electrophoretic coating film of the electrophoresis can be made out an image of the printed board. The present invention solves the problem further refining the lines in image transferring of the printed circuit board, as well as making the image of the printed circuit board more sophisticated, more accurate, more compact, and thereby electronic products can meet the miniaturized requirement.
