Abstract
A method of Printed Circuit Board (PCB) pin defect inspection is proposed in this paper. First, we input the pin location image. Then, we align images with Circle Hough Transform (CHT) [4]. Finally, we train cascade classifier with adaptive boosting [3] and Local Binary Pattern (LBP) [5], and detect pin defect to reduce false alarm rate and miss detection rate and thus enhance pin production yield rate.
