[0014] Embodiment: Please refer to Figure 1-2 , a cleaning device for PCB board production, comprising a cleaning tank 1, a conveyor mesh belt 2, a dry ice cleaning machine 3 and a plurality of diverging pipes 4. One end of the cleaning tank 1 is provided with a feeding port 5, and the other end of the cleaning tank 1 is provided with a discharging port. The conveyor mesh belt 2 is arranged in the cleaning tank 1. The PCB board is placed on the conveyor belt from the feeding port 5, and the conveyor belt conveys the PCB board from the feeding port 5 end to the discharging port end; the dry ice cleaning machine 3 is installed on the outer wall of the cleaning tank 1, and the inside of the dry ice cleaning machine 3 is filled with dry ice. A plurality of diverging pipes 4 are arrayed in the cleaning tank 1, and the diverging pipes 4 are communicated with the dry ice cleaning machine 3. A plurality of high-pressure nozzles 6 are arrayed on each diverging pipe 4. When the dry ice cleaning machine 3 is started, the dry ice powder in the dry ice cleaning machine 3 is blown by high-pressure air, and after being diverged by the diverging pipes 4, it is evenly ejected from the plurality of high-pressure nozzles 6. The dry ice powder is sprayed onto the surface of the PCB board.
