Have you heard about the 3d automated optical inspection? If you are into the AOI industry, you have seen how 2D automated optical inspection helps in different cases. 3D AOI is an advanced version of the system. An AOI system is basically any system that automatically checks the product against diverse pre-programmed criteria. The tools used in this process are optical sensors, ultrasonic sensors which are also known as X-Rays, etc. Automated optical inspection systems are used in a wide range of industries.
It is often used to ensure the necessary width and thickness of the industrial pipes. Also, it helps to check if the pipes are properly welded or not. Also, the system makes sure that all of the components are properly placed on the circuit board. Alongside these benefits, the AOI system verifies if the components are soldered on a small circuit board or not.
In the long run, the AOI system has an automated visual inspection unit that scans the devices and finds out faults in them. A variety of problems are addressed in the process. Two types of AOI are often used- 2D automated optical inspection and 3D automated optical inspection. While the first one has been in use for a long time, the second one needs some introduction.
How does 3D Automated Optical Inspection work?
3D automated optical inspection or 3D AOI is a modern invention that eases the tasks of visual inspection. It supervises the assembled printed circuit boards along with other electronic equipment in three major dimensions. The features and usage are often in contrast to 2D AOI or two-dimensional automated optical inspection. The whole process under 3D AOI includes a camera that helps to verify the quality of the items. Thus, with the use of 3D optical inspection, you can ensure the right size and proper locations.
To be more specific, a 3D AOI system involves side cameras and vertical cameras so that it can cover all of the sides of the board. Thus, it can help you understand if any of the components are skewed or flipped by any chance. If you use more advanced systems, you can identify defects e.g. excessive solder joints, etc.
