Microelectronic appearance defect detection for automated optical inspection equipment

Microelectronics refers to micro electronics, is the study of micro electronic components, electronic circuits and systems of a discipline. The field of microelectronics involves the design, manufacture and application of micro-electronic components such as microchips, integrated circuits and semiconductor devices. The development of microelectronics technology has promoted the miniaturization, lightweight and high performance of electronic products, which are widely used in computer, communication, consumer electronics, medical electronics and other fields.

In the process of microelectronics production, foreign bodies, cracks and other defects often occur, and the use of manual detection alone can not guarantee the production and accuracy. In 2024, many electronics manufacturing industries have begun to combine automated optical inspection equipment for microelectronic appearance defect detection.

Automated Optical Inspection, also known as AOI(Automated Optical Inspection), is a device based on optical principles to detect common defects encountered in microelectronics production. Mainly through the camera to scan the microelectronics and obtain the image of the area, through the visual processing technology automatically detect various appearance defects on the microelectronics. AOI automatic optical inspection equipment can greatly improve the efficiency of product inspection and ensure that the quality of the final product meets the standard, and has become an indispensable part of the electronic manufacturing process.
