发明名称 ALIGNMENT SYSTEM USING AN ELECTRONIC SCANNER
摘要 There is disclosed a method and apparatus for aligning a semiconductor device at a work station for the purpose of bonding lead wires thereto. The semiconductor device is scanned by the optical beam from a flying spot tube while simultaneously scanning a reference standard. As the semiconductor device or the work implement is moved to effect the desired alignment, the flying spot is zoomed to increase its magnification and thereby effect more accurate alignment.
