More Information
Summary:The invention discloses a device for corroding a circuit board. The device comprises a corrosion pool, a loading stage, a first motor, a signal emitter, a receiving device, an impeller and a second motor, wherein longitudinal racks are arranged at two sides of the inside of the corrosion pool; the corrosion pool is used for loading a corrosive liquid; gears are arranged at two sides of the loading stage respectively; the gears are meshed with the racks; a circulating hole is formed in the middle of the loading stage; a plurality of bearing seats are arranged on the end surface of the loading stage; a threaded hole is formed in one bearing seat; the first motor is embedded into the loading stage and is connected with the gears to drive the gears to rotate; the signal emitter is arranged outside the corrosion pool; the receiving device is connected with the first motor and is used for receiving a signal emitted by the signal emitter to control the first motor to rotate and stop; the impeller is arranged below the circulating hole; and the second motor is connected with the impeller to drive the impeller to rotate. The device is capable of automatically corroding the circuit board.
