AOI (Automated Optical Inspection) that is, automatic optical inspection, is a widely used in the electronics manufacturing process of automated inspection technology, its role mainly includes the following aspects:

1. Detect product quality: AOI equipment can be used in the electronics manufacturing process of PCB (Printed Circuit Board, Printed Circuit Board) and assembled electronic components for automated optical inspection to detect product quality and manufacturing defects. Through high-resolution optical imaging systems and image processing algorithms, AOI equipment can quickly and accurately detect defects on the product surface, soldering quality, component positional deviations and other issues to ensure that the product meets quality standards.

2. Improve production efficiency: AOI equipment can replace the traditional manual visual inspection to achieve automated rapid inspection of products, greatly improving the inspection efficiency and throughput rate of the production line. Through real-time inspection and automatic classification, AOI equipment can help manufacturers find and deal with product quality problems in a timely manner, reduce the generation of defective products and improve production efficiency and product quality.

3. Data analysis and traceability: AOI equipment is usually equipped with data acquisition and analysis functions, capable of recording and analysing data from the inspection process, providing a basis for optimisation and improvement of the manufacturing process. At the same time, AOI equipment can also trace back each product and record its inspection results and production process information, which helps to track and solve quality problems and improve the controllability and traceability of the manufacturing process.

In general, the role of AOI equipment in electronic manufacturing mainly includes product quality inspection, production efficiency and data analysis and traceability, is an indispensable and important equipment in the electronic manufacturing process, to improve product quality, reduce manufacturing costs and improve production efficiency is of great significance.
