发明名称 METHOD AND SYSTEM FOR DETECTING DEFECTS ON A PRINTED CIRCUIT BOARD
摘要 <p>A method and a system for detecting surface defects on electronic circuits, such as Printed Circuit Boards (PCB), are described herein. The method first comprises identifying contours on a digital image of the PCB. Then anomalies are detected on the PCB image by comparing the identified contours to contours on a vectorial model of the PCB. Each detected anomally is compared to manufacturing data to verify it if corresponds to a defect.</p>
