Template based defect detection of flexible printed circuit

This study presented a research on machine vision inspection to define defects on flexible printed circuit (fpc). the images were subjected to image processing system where an elimination-subtraction method used. in this algorithm,7 types of fpc defects defined and simulated in the system using specimen 1 and processing time taken for both side inspection was 3.3s. then,the commercial patent design of fpc was tested as specimen 2 to define short circuit defects on it. the processing time taken by this algorithm on specimen 2 was 0.28s. comparison on manual inspection and machine vision implementation were carried out and greatly resulted on shorten inspection time to 59.7%. this result shows significant contribution in increasing the efficiency of fpc inspection process. © 2016 penerbit utm press. all rights reserved.
