Traditional manual inspection has the disadvantages of slow speed, low efficiency and high labor cost, which makes PCB unable to adapt to mass production. Intelligent detection of printed circuit plate plays an important role in the development of modern electronic devices and the miniaturization and visualization of circuits. In this environment, how to achieve high efficiency, accuracy and speed through low cost is of great significance to the detection of chip circuit board. Optical detection technology has the advantages of high speed, high precision and low cost, and is gradually replacing the traditional manual detection technology. This design has completed the image acquisition, smooth filtering, noise reduction, image enhancement and edge extraction of the video collected by the camera, so as to realize the clear processing of the butt pad, to solve the problem of low precision and slow speed of the traditional printed circuit board. This design is based on digital image processing, the application of MATLAB software, the completion of the printed circuit board solder pad for intelligent detection and edge clear design, to improve the production efficiency of printed circuit board and reduce the production cost.
