Automatic optical inspection (AOI) uses high-speed, high-precision visual processing technology to automatically detect various mounting errors and welding defects on PCBA. AOI optical inspection is a very important inspection link in SMT patch production. So how much do you know about AOI optical inspection?

AOI optical inspection automatically scans the PCB through the camera to capture and image the components on the PCB. It mainly detects the printed solder paste, component status on the PCB, solder joint shape and defects, etc., and comprehensively compares it with the qualified parameters of the database program through software processing to ensure Determine whether the component placement is qualified. Once the AOI finds a defective product, the inspection equipment will mark the location of the defective product and automatically remove the defective product.

AOI optical inspection is an indispensable and important inspection link in PCBA production. Program production and post-inspection can quickly and accurately select defective products for later maintenance, thereby reducing the product defect rate.
