The new Spectroline erasing system designed to meet high-volume production requirements ensures fast and complete eraser (highest UV intensities) of programmed memory from every EPROM, chip or wafer in 90 seconds.
According to Spectronics press release, the Spectroline PC-9920A UV EPROM/Wafer Erasing System has an operating UV intensity that is up to 60 per cent greater than competitors’ systems with a nominal 254 nm irradiance of 70,000µW/cm² over a 36 x 24 in (91.4cm x 61cm) erasing area. Adding further the release states, “The PC-9920A’s extra wide and deep drawer, measuring 36.75 x 28 x 1.75 in (93.3 x 71.1 x 4.4 cm), provides for easy loading of wafers, PC boards, open-faced stocking tubes and metric cards. Heavy-duty slides allow the drawer to open fully for greater access to the loading area. Adjustable tray inserts can be set to varying heights to ensure optimum UV exposure. The quick load/unload tray allows safe handling and ensures proper positioning and pre-loading of EPROMs, PC boards, metric cards and wafers. It accommodates an extra-large load capacity of 24–inch (150mm) wafers.”
