Abstract

The invention relates to the technical field of PCB production. The invention further discloses etching equipment for PCB production. which comprises a shell, the upper end of the shell is fixedly connected with a lifting motor; the lower end of the lifting motor penetrates through the side wall of the shell and is fixedly connected with a lifting rod; the lower end of the lifting rod is fixedly connected with a swinging mechanism; the lower end of the swing mechanism is fixedly connected with a supporting plate, the lower end of the supporting plate is fixedly connected with two fixing blocks, the side walls of the two fixing blocks are fixedly connected with inserting rods, the rod walls of the two inserting rods are connected with the same PCB in a sleeving mode, and the ends, away fromthe fixing blocks, of the inserting rods are connected with limiting covers in a clamped mode. The contact area between the copper-clad surface of the PCB and the etching liquid can be increased, theetching efficiency of equipment is improved, the requirements of people are met. Meanwhile, the situation that etching is not thorough is reduced, and people can use the copper-clad surface of the PCB conveniently.

Description

technical field [0001] The invention relates to the technical field of PCB board production, in particular to an etching device for PCB board production. Background technique [0002] Etching is to spray the etching solution evenly onto the surface of the copper foil through the nozzle under certain temperature conditions, and undergo redox reaction with the copper that is not protected by the etch resist, and react the unnecessary copper, expose the substrate and then strip it. Forming the lines after film treatment. [0003] A PCB board etching device proposed in the patent authorization announcement number CN 208581402 U, a PCB board etching device of the present invention, can detect the concentration of copper ions in the etching solution in real time through a copper ion concentration measuring instrument, and through the water pump Supplementing the etching solution can not only accurately replenish the etching solution to ensure product quality, but also save labor ...
