It has to be right because the rest of the process can't make up for improper solder placement. Next month: pick-and-place machines! SMT Robert Voigt is VP of global sales at DDM novastar Inc. He may be reached at rvoigt@ddmnovastar.com. Materials first developed at oregon State university more than a decade ago may be about to shake up consumer electronics. Transparent transistors were invented by oSu researchers in 2002. one of the most im- portant of the semiconductors is based on in- dium gallium zinc oxide, or IgZo. "amorphous oxide semiconductors appear well-positioned to significantly impact a $100 billion industry," said John Wager, holder of the Michael and Judith Gaulke Chair in the oSu School of electrical engineering and Computer Science. Transistors made using IgZo consume much less standby power. cell phones might be created that only need charging once or twice a week.
