  • Method and system for detecting defects on a printed circuit board
    Patent number: 6771807
    Abstract: 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 anomaly is compared to manufacturing data to verify if it corresponds to a defect.
    Type: Grant

    Date of Patent: August 3, 2004
    Assignee: Solvision Inc.
    Inventors: Alain Coulombe, Michel Cantin, Louis Bérard, Jonathan Gauthier
