Today, China has become a major producer in the PCB industry, and its PCB production capacity ranks among the top in the world. However, there is a gap in PCB technology level compared with foreign countries, and the products are mainly mid- to low-end products. Therefore, in order to enhance its own technological advantages and improve the profit level of the PCB industry, it is necessary to start from aspects such as design and manufacturing, product structure, process flow, equipment improvement, and production efficiency, break through the existing technical barriers, and carry out improvements and innovations to enhance its competitiveness in the PCB industry.

[0003] In the inner layer process of the circuit board, due to the excessive number of laminated sheets of multi-layer boards with four or more layers, in order to ensure the reliability of the multi-layer board in subsequent processing and production, a target drilling link is set in the inner layer process. A target drilling machine is used to punch holes in the multi-layer board with four or more layers after de-filming, and these drilled target holes are used as positioning references. These target holes are generally at the top or bottom of the circuit board. The punching positions are identified through a CCD image system, and then the drilling operation is completed using a drill bit.
