Abstract :
Notable advances during 1992 are reviewed. They include improved precision in computerized numerical control (CNC) for machine tools; easier, high-level programming for programmable logic controllers; faster and more efficient machine vision; reduced false accept and reject ratios in X-ray laminography for the examination of solder joints, particularly in surface-mounted boards; and high-wattage power electronic devices. The latter offer lower voltage drop when turned on, plus the ability to control motors and other manufacturing equipment with a virtually unity power factor on utility lines
