Automatic optical inspection equipment is already a must in every electronic factory, and it is constantly being enhanced and updated to improve its capabilities. This inspection equipment is used in many industries, including printed circuit board manufacturing, bare board inspection, solder paste printing, and assembly. For PCB assembly, the AOI system will check the placement and soldering of the components, and feedback potential problems in the test to our operators. From wrong parts to bad welded connections. The automatic optical inspection (AOI) system will check your PCBA. The system can quickly evaluate thousands of details that cannot be captured by the naked eye, and feedback any detected problems to the operator.

AOI PCB inspection equipment relies on high-resolution camera systems and different lighting sources, such as fluorescent, LED, ultraviolet, and infrared, to capture a series of images. These images are processed by the system, which is programmed to inspect different details of the assembled board. The AOI system will scan each assembly board and compare these images with the images of the standard board stored in the file. When it finds inconsistencies with the standard board, it will mark these areas as possible defects so that technicians can inspect them in more detail. This will better ensure product quality.
