  • Lead inspection system for surface-mounted circuit packages
    Patent number: 4875778
    Abstract: An electro-optical system for detecting selected geometrical properties of leads of circuit packages of the surface-mounted type. The system employs a horizontally-arranged linear array of photosensitive elements which is moved in a direction perpendicular to a reference surface and operated to provide a series of one-dimensional horizontal scans along the leads.
    Type: Grant
    Filed: April 25, 1988
    Date of Patent: October 24, 1989
    Inventors: Richard J. Luebbe, H. Kenneth Hopkins
  • Lead inspection system for surface-mounted circuit packages
    Patent number: 4875779
    Abstract: An electro-optical system for detecting selected geometrical properties of leads on circuit packages of the surface-mounted type. The system employs a vertically-arranged linear array of photosensitive elements which is carried horizontally parallel to a reference surface and operated to provide a series of one-dimensional scans vertically along the leads.
