The invention discloses an apparatus for PCB corrosion. The apparatus comprises a corrosion pool divided into two layers, two groups of lead screws, a first motor, a loading platform, a first impeller, a second motor, a plurality of second impellers, and a plurality of third motors. The two groups of lead screws are arranged at the two sides of the bottom of the corrosion pool in a rotatable mode; one end of each lead screw extends into the second layer and the other end extends out of the corrosion pool. The first motor is arranged in the second layer of the corrosion pool and is connected with one lead screw group to drive the lead screws to rotate. A group of threaded holes is arranged at each of two sides of the loading platform and the two groups of threaded holes are connected with threaded ends of the two groups of lead screws movably and correspondingly; a circulating hole is formed in the middle of the loading stage; and a plurality of bearing seats are arranged on the end surface of the loading platform and a threaded hole is formed in one bearing seat. The first impeller is arranged below the circulating hole. The second motor is connected with the first impeller. The multiple second impellers are arranged at the inner peripheral wall of the corrosion pool respectively. And the multiple third motors are connected with the second impellers. With the apparatus, a PCB can be corroded automatically.
