Background

PCB boards, also known as printed circuit boards, are providers of electrical connections for electronic components. Its development has been over 100 years old; the design of the method is mainly layout design; the circuit board has the main advantages of greatly reducing errors of wiring and assembly, improving automation level and production labor rate, and being divided into single-layer boards, double-sided boards, four-layer boards, six-layer boards and other multi-layer circuit boards according to the number of 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.

PCB drilling is a process of PCB plate making and is also a very important step. The drilling is to drill a needed through hole on the copper-clad plate for providing the functions of electrical connection and fixing devices. If the misoperation, the device can not be fixed on the circuit board, can influence its use, in the work of punching of multiply wood, need to stack up the plank to its upper and lower both ends, fix on the plank of upper end with the pipe position nail, bore the drill bit into the multiply wood through the hole of pipe position nail during, this kind of protection mode that punches, the operation process is loaded down with trivial details, and wastes time and energy, consequently, prior art exists not enoughly, needs to improve to this.
