The invention discloses a self-fastened PCB board transferring cart which comprises a support frame, wherein the support frame is composed of two short cross beams, two long cross beams and four positioning pillars, the short cross beams, the long cross beams and the positioning pillars are assembled to form a cuboid-shaped frame, the bottom end and top end of an external side border of the support frame are each provided with a guide rail along the long cross beam direction, and a horizontal open slot is formed on the guide rail; and a sliding plate I and a sliding plate II which can slide along the long cross beam direction are arranged in the support frame, the sliding plate I and the sliding plate II are respectively located on both sides of a middle pillar, and multiple pressure springs are uniformly distributed between the sliding plate I and the sliding plate II. Because the transferring cart disclosed by the invention is provided with the sliding plates and the springs, the distance between one positioning pillar and one sliding plate can be arbitrarily adjusted, so that the transferring cart is applicable to the storage of PCB boards with various sizes, then an effect of self-enclasping PCB boards is achieved, and PCB boards are convenient to load and unload. The invention also discloses a specially-made antistatic coating. By use of the specially-made antistatic coating, the antistatic effect and the anti-corrosion effect are longer, and the service cycle of the antistatic coating is prolonged.
