I.C.T Automated Optical Inspection (AOI) to Improve SMT Line Efficiency

Industry News | 2022-10-12 08:07:17.0

I.C.T Provide SMT Production Line solutions with Automated Optical Inspection (AOI) AOI is short for Automated Optical Inspection, which is widely used in the electronics industry to check the appearance of PCBA assembly at the back end of the circuit board assembly line. The basic principle of AOI is to judge whether the object to be tested meets the standard by comparing whether there is a large difference between the object to be tested and the standard image by using image technology. AOI emits a 4-color light source to the PCBA board, which is automatically scanned by an industrial camera for catastrophic failures, such as missing components or quality defects. Therefore, the quality of AOI depends on the image imaging ability, algorithm parsing ability and image discrimination technology. I.C.T AOI has done well in these aspects.
