The invention discloses a data processing method for integrated circuit manufacturing, which belongs to the technical field of circuit board detection; compared with traditional image detection, laser detection can realize non-contact long-distance measurement with high speed; optical imaging equipment and The combination of line laser detection can construct a complete circuit board image, and then cooperate with the optical image to realize accurate automatic detection; the purpose of the method of the present invention is to provide an efficient and convenient processing of specific data after the combination of the above detection methods The logic of the method uses different algorithm calculation examples to preprocess, analyze, and match different acquired images. The data processing method constructed by the present invention can better integrate the data of the two parts, and more accurately determine the integrated circuit of the circuit board. The shape or size of the board or the position of the hole or the defect of the circuit board can help to improve the efficiency of the circuit board processing.
Description
technical field [0001] The invention belongs to the technical field of circuit board detection, and particularly relates to a data processing method for integrated circuit manufacturing. Background technique [0002] Optical automatic testing equipment, also known as AOI testing equipment, has become an important testing tool and process quality control tool for the electronics manufacturing industry to ensure product quality. AOI (Automatic Optical Inspection), in the SMT manufacturing process, AOI equipment uses high-speed and high-precision X-Y work platform and vector feature vision processing technology to automatically detect various placement errors and welding defects on PCB boards. The smallest component that can be detected is 0.1-0.05mm chip components and IC components with a pin spacing of 0.3mm, AOI equipment can correspond to the quality inspection of red glue process, solder paste process, and soldering after wave soldering of the plug-in section. However, t...
