Automated Optical Inspection (AOI) Systems for PCB Manufacturing
Automated optical inspection (AOI) systems perform visual inspections of printed circuit boards (PCB) during manufacturing in which a camera is used to scan the board in extremely fine detail to check for any defects or failures. AOI is the integration of optics, mechanics, electronic control, and software to replace the human eye. In the real world, PCBs are getting smaller and more complex; even a relatively simple board can be made up of literally thousands of soldered components. AOI monitors the quality of PCB production and corrects them in the process flow, which is a key to success in today's competitive PCB production environment.
AOI systems are commonly used in the production of all kinds of products but are especially important for monitoring printed circuit boards for defects and accurate measurements beyond the capabilities of a human inspector. They are able to detect a variety of surface feature defects, such as nodules, scratches, stains, open circuits, and the thinning of soldered joints. However, the development of an AOI system for PCBs is unlike an AOI general purpose system. There are some specific features that are only for the development of an AOI system used for PCB manufacturing. To provide truer co-planarity inspection capabilities and volumetric inspection data, an AOI system requires different types of cards to connect to devices such as robotic arms and CCD cameras. For the AOI system to keep pace with increasing manufacturing speeds, a powerful Graphics Processing Unit (GPU) card is needed.
Investing in AOI systems means less waste, a lower cost of production, and maximized yields. Advantech server boards not only deliver the necessary power for the AOI system, they also work in a 0 ~ 40°C temperature ranges. Another reason why the customer chose Advantech was the continued support beyond the longevity product life of up to seven years. We believe that our server motherboards and industrial computer chassis will meet both the current and future needs of AOI customers.
