(Summary description)AOI automatic optical inspection instrument Automated Optical Inspection (AOI, Automated Optical Inspection) 　　I. Definition 　　Using high speed and high precision vision processing technology to automatically detect different kinds of mounting errors and soldering defects on PCB boards. 　　PCB boards can range from fine pitch high density boards to low density large size boards, and can provide in-line inspection solutions to improve production efficiency and solder quality. 　　By using AOI as a defect reduction tool, errors can be found and eliminated early in the assembly process to achieve good process control. Early detection of defects will prevent bad boards from being sent to subsequent assembly stages, and AOI will reduce repair costs by avoiding scrapping unrepairable boards. 　　Second, the main features 　　1) High-speed inspection system 　　Independent of PCB mounting density 　　(2) Fast and convenient programming system 　　- Graphical interface for 　　-Automatic data inspection with mounting data 　　-Fast editing of inspection data using component database 　　3）Use of a wealth of special multifunctional inspection algorithms and binary or grayscale 　　(3) Inspection using a wide range of dedicated multifunctional inspection algorithms and binary or grayscale optical imaging processing technology 　　4) Automatic correction of the detection window according to the instantaneous change of the position of the inspected component 　　Automatic correction to achieve high accuracy detection 　　(5) Detection by marking directly on the PCB with ink or by graphical error representation on the operation display 　　on the operating display with graphic errors to check the detection of electricity
