PCB 검사를 위한 비젼 시스템 개발 = The development of Vision system for the inspection of end product PCB

다국어 초록 (Multilingual Abstract)

In this paper, we proposed the vision system that inspects automatically missing/wrong insertion of electronic components and the scratch filth on the end product of PCB. The system consists of the software part that inspects PCB products and the hardware part to control XY-table and CCD camera. The hardware part controls the XY-table to import the product images through the CCD cameras. The imported image are inspected by software part. The front side image of product is acquired by 1 times image and back side images are acquired by 4 times image. After the preprocessing through the noise removing and inspection area extraction, the inspection for front and back side components is done. In the inspection processes, we respectively use the features of electronic components, In the simulation, the proposed system has a good performance.
