The circuit board of electronic products is becoming more and more complex, the number of components is increasing, and the difficulty of circuit board detection has also increased greatly. There may be a large number of electronic components and circuit connections on a complex circuit board, and the relationships between these components and connections are intricately intertwined and difficult to inspect with traditional manual inspection channels. In addition, the manufacturing accuracy of PCB circuit boards is very high, and for some key components, the deviation of its position and size will have an impact on the efficiency of the circuit, so the requirements for detection accuracy are also very high. Moreover, the traditional manual inspection channel requires a lot of time and manpower, and is inefficient, which is difficult to meet the high-speed production needs of modern industry.
