Aehr Test Systems Receives FOX™-15 System Order

FREMONT, Calif., July 11, 2012 (GLOBE NEWSWIRE) — Aehr Test Systems (Nasdaq:AEHR), a worldwide supplier of semiconductor test and burn-in equipment, announced today that it has received orders for a FOX-15 wafer-level burn-in system and a WaferPak cartridge aligner from a leading communication equipment manufacturer.

“We are very pleased that this customer has selected our FOX-15 wafer-level burn-in system for their production burn-in solution. We worked closely with them to design and supply a complete solution to meet their needs. The complete solution includes our patented WaferPak cartridge capable of burning-in over 10,000 die per wafer, an aligner used to align the wafer to the cartridge, the FOX-15 system capable of burning-in multiple wafers simultaneously and the program to stress the wafers. This complete solution, we believe, is very cost effective compared to package burn-in alternatives,” said Larry Anderson, vice president of worldwide sales of Aehr Test Systems.

Anderson added, “As this customer’s production needs increase, we expect they will require additional WaferPak cartridge capacity. These orders extend our FOX technology into the communications equipment industry and complement FOX systems already in use in the memory and automotive industries.”

The FOX-15 wafer-level burn-in system is a member of the FOX family of full wafer contact systems. The FOX-15 system provides cost effective test and high reliability burn-in of up to 15 wafers in parallel for applications such as automotive ICs, DRAMs, flash memory, sensors and VCSELs (laser diodes). The FOX-15 system performs burn-in of bare die at the wafer level so that Known Good Die (KGD) can be produced for stacked die and through silicon via (TSV) applications.
