AOI (Automatic Optical Inspection)

AOI uses high-resolution cameras to capture PCB images from different angles, and then compares them with reference images to detect any defects or inconsistencies. Therefore, manufacturers can quickly identify problems in the production line without slowing down production time or affecting quality control.

By utilizing AOI in the PCB manufacturing process, manufacturers can detect errors before they become costly issues. It helps reduce waste and improve overall efficiency, as it can quickly identify and discard PCBs that can pass inspection without AOI. Manufacturers can use AOI technology on PCB production lines to meet strict quality standards while ensuring consistency of the final product.

In our PCB process, we mainly use AOI to inspect subtle defects in copper wires, such as copper wire voids. In addition, AOI is also used in solder mask processes to detect solder mask issues.

Therefore, we believe that Automatic Optical Inspection (AOI) is an important component of PCB manufacturing to ensure that PCBs are defect free and meet the highest quality standards.
