Electrolytic etching production line

Abstract

The invention relates to the technical field of electrolytic etching, and particularly provides an electrolytic etching production line which comprises a rack, at least one developing tank arranged in a developing area, at least one electrolytic tank arranged in an electrolytic area and spraying mechanisms arranged in the developing tank and the electrolytic tank, wherein the rack comprises a feeding area, a developing area, an electrolysis area and a discharging area; the adjacent developing tank and electrolytic tank communicate in a sealed mode, and the spraying mechanisms are used for spraying solutions into the corresponding tanks respectively so that the solutions in the tanks can be in a flowing state. The spraying mechanisms are arranged in the developing tank and the electrolytic tank, the spraying mechanisms are used for spraying the solutions to anode plates in the corresponding tanks, the solutions in the tanks are in a flowing state, it is guaranteed that the density of the solutions in the tanks is in a uniform state, and after the anode plates are soaked in the solutions, the solutions with uniform density can uniformly soak the anode plates, so that the problem of poor electrolysis and development effects when the anode plates are horizontally soaked in the tank body due to the deposition phenomenon of the solution is solved.

Description

technical field [0001] The invention relates to the technical field of electrolytic etching, in particular to an electrolytic etching production line. Background technique [0002] Electrolytic etching is used for the first time in the production process of PCB boards. It refers to the electrolysis of PCB boards. The board to be etched is used as the anode, and the stainless steel plate or pure copper plate is used as the cathode. The anode is connected to the positive pole of the power supply, and the cathode is connected to the negative pole of the power supply. The anode and the The cathodes are immersed in an electrolyte solution. When the current passes through the electrode and the electrolyte solution, an electrochemical reaction occurs on the surface of the electrode and in the electrolyte solution. This reaction is used to remove the exposed copper on the PCB surface to be etched, so that the exposed copper on the PCB surface is corroded. . When the power of the e...

Problems solved by technology

[0004] Therefore, the technical problem to be solved by the present invention is to overcome that in the electrolytic etching production line in the prior art, when the anode plate is correspondingly processed, the workpiece is processed correspondingly by means of soaking the anode plate horizontally in the solution. After a period of treatment, the solution will deposit, making the density of the solution in the tank uneven, so that when the anode plate is soaked in the solution, the solution cannot uniformly soak the anode plate, resulting in electrolysis and development of the anode plate. less effective defects
