Wherein the fabrication of the electrode drive affects the accuracy of the implantation of the electrode into the brain region. The traditional electrode manufacturing is to sequentially penetrate the copper columns and the screws into corresponding holes on the PCB in the manufacturing process by assembling the PCB, the screws, the square copper columns and the like to serve as electrode driving devices, after the position is adjusted, epoxy resin is coated on each contact point of the copper columns and the PCB, and the positions coated with the epoxy resin are heated by a hot air gun so as to promote hardening of the epoxy resin. Since the electrodes are to be implanted precisely in the brain region of the mice, the assembled PCB boards are required to be relatively parallel. And the uppermost plate is tightly propped against the head of the screw so as to prevent the electrode wire from shaking up and down. However, the support plates assembled by the scattered plates are often not parallel, so that the screws and the electrode wires are inclined to different degrees due to the misalignment of the positions of the holes. The board can be blown askew by the wind force in the process of heating the glue by using the hot air gun, and the epoxy resin can be blown onto the screw, so that the screw is stuck on the PCB board and cannot step. The operation process is also relatively complex and fine.
