The Spectroline PC-4420A UV EPROM/wafer-erasing system is a high-intensity unit with an extra-large load capacity. It produces a nominal initial shortwave UV (254-nm) intensity of 46,000 µW/cm² to ensure quick and complete erasure of programmed memory from every EPROM chip or wafer. This high-efficiency unit can complete an erasing cycle in 4 minutes.
The PC-4420A uses four high-intensity ozone-free mercury vapor quartz grid lamp assemblies mounted on specular aluminum reflectors. Internal cooling fans control the cabinet temperature to ensure optimum UV intensity, maintain uniform output, and provide reliable erasing conditions. The fans also prolong the life of the grid lamps.
The cabinet’s large drawer has an extra-large load capacity of 336 individual 24-pin EPROMs. It can also accommodate PC boards, metric cards, and silicon wafers, as well as open-faced stocking tubes. A removable tray insert is height adjustable to maintain ideal UV exposure distance. Optional tray inserts are available to accommodate either 6-in. (152-mm) or 8-in. (203-mm) wafers. A safety interlock prevents operation unless the loading drawer is fully closed.
