PC-9920A UV EPROM/wafer erasing system is for high-volume production. Reportedly has an operating UV intensity up to 60% greater than other systems. Drawer measures 93.3 x 71.1 x 4.4cm; provides for loading of wafers, printed circuit boards, open-faced stocking tubes and metric cards. Adjustable quick load/unload tray inserts can be set to varying heights. Accommodates load capacity of 150mm wafers. PC-9920A-LT system includes light tower; has red/yellow/green signals that indicate the mode status at every stage of operation. Both systems use nine ultra-high intensity, ozone-free, low-pressure mercury vapor quartz grid lamp assemblies. UV grid lamps reportedly increase throughput. Has nominal 254nm irradiance of 70,000 µW/cm² over a 91.4 x 61cm erasing area.
