It is usually used as the basic structure of electronic products to support and arrange electronic components so that they can be connected to each other and realize circuit functions. Conductors, circuits, and other electronic components are printed on the board through printed circuit technology to form a complete circuit. During the production process of circuit boards, punching is required, so a punching device needs to be designed to punch circuit boards.
