Extra-Large Capacity Erasing Systems

The PC-8820B, PC-8820B-LT, PC-8820C-LT, PC-9920A, PC-9920A-LT and PC-10020-LT systems are the next generation of UV EPROM/wafer erasers!

Superior UV intensity! Faster erasing times! Larger load capacities!

Specially designed to meet the critical production requirements of high-density EPROMs and wafers, these “super-capacity” units incorporate the latest technological advances in the industry to ensure the highest UV intensities, fastest erasing times and improved safety. Each system is engineered for maximum irradiance uniformity, boasting a nominal initial UV intensity output of 70,000 μW/cm² — producing the quickest and most complete erasure of programmed memory.

They provide erasing cycle times as fast as 90 seconds!

Where to Buy

These units include the same features as our other PC-Series erasing systems plus these additional innovations:

  • Advanced UV lamp design — Ultra-high intensity short-wave UV (254 nm), low-pressure mercury vapor quartz grid lamp assemblies meet the highest design and performance specifications
  • Increased operating intensity — At least 60% greater throughput than competitive systems
  • Exclusive quick load/unload tray — Facilitates safe handling, ensures proper positioning and allows pre-loading of EPROMs, PC boards, metric cards and wafers
  • Digital timer — Pre-settable by user to minimize operator error and provides automatic shut-off at the end of the erasing cycle. May be set for hours, minutes or seconds
  • Improved internal cooling system — Provides outstanding airflow path and maximum uniform UV output — dramatically extending the life of the grid lamps
  • Two-piece, modular cabinet design — Rugged, anodized aluminum and stainless steel construction. Ensures better productivity, safer handling and simplifies storage and maintenance
  • Temperature gauge — Shows when unit has acclimatized to its surroundings and reached operating temperature
  • Special hood attachment — Provides improved air exhaust and added shielding from UV exposure
  • Manual fan speed control — Allows fan speed adjustment in upper unit to stabilize temperature according to room environment

Extra-Large Drawer Load Capacity!

 

Larger drawer dimensions maximize load capacity of individual EPROMs, wafers and PC boards. Accommodates a variety of loading formats.

  • Extra deep to permit loading of PC boards and metric cards
  • Extra wide to accept open-faced stocking tubes for mass chip erasing without unloading
  • Heavy-duty slides allow drawer to open fully for greater access to loading area
  • Accommodates PC boards, metric cards and silicon wafers ranging from 6 to 12 inches (152 – 305 mm)
eprom_erasing_system_air_flow_diagramAdjustable tray inserts, with or without wafer fixtures, designed to handle wafers ranging in size from 6 to 12 inches (152 – 305 mm) are available as an option (sold separately). Custom features are also available on most units by special order. Spectronics Corporation can design and manufacture a system to meet your specific production and budget requirements.
