  • Inspection method for unpopulated printed circuit boards
    Patent number: 6340817
    Abstract: A method and apparatus for inspection of unpopulated printed circuit boards is disclosed. A printed circuit board is mounted on a mobile base capable of scanning on at least one direction. During a scan, the printed circuit board moves with respect to a heater and a portion of the board's surface, including both tracks and substrate, is heated. After heating, but within seconds of removing the heat source, the board surface is analyzed by an infrared (IR) sensitive camera. The different intensities of IR emissions allow for discrimination between the traces and the substrate and provide a means of detecting defects on the board. Defects are detected either by comparison to a database used for production of the boards or by design rule checking.
