[0002] In the prior art, PCB is the abbreviation of Printed Circuit Board, i.e., printed circuit board, which is a circuit board commonly used in various electronic products, commonly known as a hard substrate. The general processing method of PCB is to laminate copper foil on thermosetting resin and glass fiber, and develop and etch the circuit on the copper foil by film printing, then perform circuit detection, and then perform the processing process of shape and holes. The upper surface and / or lower surface of the PCB are provided with metal circuits, such as copper circuits, and the exposed parts of the metal circuits are even tinned or gold-plated to reduce contact resistance or increase the welding performance of solder, which shows the importance of the flatness of the metal surface. At present, the PCB board stamping process uses stamping equipment and stamping dies to perform punching or punching operations on part or all areas of the PCB board. However, the existing stamping equipment is prone to stamping position deviation during the processing due to the frequent use of the stamping machine, resulting in the upper die or lower die or the PCB board being damaged due to excessive force or excessive deviation or inaccurate position during stamping, and the scrap rate is high.
