  • Video bond lead locator
    Patent number: 5125036
    Abstract: An image processing system and method are used to ascertain the position of lead frame beams on a semiconductor lead frame prior to the formation of wire bonds to those lead frame beams. The lead frame beams are illuminated by a light source and light reflected from the lead frame beams is detected. Digital data representative of the reflected light is generated and stored in a memory. A control means defines corridors in that memory which are analyzed to define the position of the lead frame beams and to distinguish light reflected from the lead frame beams themselves from light reflected from interlead ceramic or glasslike material.
