The circuit board can be divided into single-sided boards, double-sided boards, four-layer boards, six-layer boards and other multilayer circuit boards according to the number of the layers of the circuit board. Since printed circuit boards are not typical end products, they are somewhat confusing in the definition of names such as: the motherboard for a personal computer is called a motherboard and cannot be directly called a circuit board, and although the circuit board exists in the motherboard, the motherboard is different from the motherboard, so that the two aspects cannot be said to be the same when evaluating the industry. For another example: because of the integrated circuit components mounted on the circuit board, the news media is called an IC board, but it is not substantially identical to a printed circuit board. By printed circuit board we generally say bare board-i.e. a circuit board without upper components.
The existing PCB is usually installed at the bottom in the equipment shell by adopting screws, so that the circuit board needs to be punched, but when the circuit board is punched, the punching precision is easily influenced due to the displacement of the circuit board; and because of lacking the positioning mechanism, a plurality of holes drilled by the drilling machine are not on the same horizontal line or the same vertical line, which greatly influences the beauty of the circuit board.
