The invention discloses a filter pumping loss prevention structure for an electroplating printed circuit board; a liquid inlet pipe is communicated between a filter pump suction inlet of a filter and a liquid outlet of an electroplating tank; a liquid outlet pipe is communicated between a filter pump liquid feed port and a liquid inlet of the electroplating tank; more than at least one of the liquid inlet of the electroplating tank, the liquid inlet pipe and a filter pump is provided with a filtering screen which can intercept larger impurities in electroplating liquid so that the impurities can be prevented from entering the filter pump, the damage ratio of the filter pump can be effectively reduced, and the using environment of the filter can be improved, thus prolonging the service life of the filer.
Description
technical field [0001] The invention relates to a structural improvement of equipment used in a printed circuit board electroplating production line, in particular to a structure that can improve the use environment of the filter and reduce the damage rate of the filter pump. Background technique [0002] Electroplating can not only decorate and protect many industrial products, but also meet some special functional needs. Electroplating is to immerse the plated part in the plating solution of metal salt as the cathode, and the conductor or semiconductor as the anode. After the power is turned on, the desired coating is deposited on the surface of the plated part. [0003] Electroplating is an essential part of the printed circuit board (PCB) production process. In the electroplating process of printed circuit boards, it is generally necessary to filter the electroplating solution to remove impurities in the electroplating solution and ensure the quality of the coating.
