Novel corrosion-resistant PCB

The utility model relates to the technical field of PCBs, in particular to a novel corrosion-resistant PCB which comprises a corrosion-resistant PCB body, two opposite side ends of the corrosion-resistant PCB body are fixedly connected with fixing blocks, the upper end faces of the fixing blocks are fixedly connected with limiting sliding blocks, the lower end faces of the fixing blocks are provided with limiting sliding grooves, the limiting sliding grooves are matched with the limiting sliding blocks, and the limiting sliding blocks are arranged in the limiting sliding grooves. The end of the side, away from the corrosion-resistant PCB body, of the limiting sliding block is connected with an elastic limiting assembly, the side end, away from the corrosion-resistant PCB body, of the fixing block is provided with a plurality of limiting holes matched with the elastic limiting assembly, the limiting holes communicate with the limiting sliding grooves, and the side, away from the corrosion-resistant PCB body, o
