Aehr Test Systems Announces Shipment of FOX-1P™ Single Wafer Test Systems to Lead Customer for Production Test and Burn-In Application

FREMONT, Calif., Sept. 01, 2016 (GLOBE NEWSWIRE) — Aehr Test Systems (NASDAQ:AEHR), a worldwide supplier of semiconductor test and burn-in equipment, today announced that it has begun production shipments to its initial lead customer for its FOX-1P single wafer test system and has shipped and received acceptance on the first production systems previously ordered by this customer. This follows the company’s announcement in July of the shipment of the initial FOX-1P system to this customer. The FOX-1P system is Aehr Test’s next generation single wafer test system for high volume production and early failure rate (EFR) test. Aehr Test expects to complete shipment of the remaining systems in backlog to the customer’s production site within its fiscal second quarter ending November 30, 2016.

Gayn Erickson, President and CEO of Aehr Test Systems, commented, “We are very pleased to begin shipment of production FOX-1P systems to this lead customer. In addition, we are pleased that this customer has expanded test applications for this system to include microcontrollers in addition to the initial target of non-volatile memories.”

The FOX-1P wafer test system is a member of Aehr Test’s next generation FOX-P family of wafer level test and burn-in systems and has more than 16,000 “Universal Channels” (I/O, Device Power Supply (DPS) or Per-pin Precision Measurement Unit (PPMU)). With the highest channel count available in the ATE industry, the flexibility of Aehr Test’s Universal Channel architecture, and the ability to perform both functional pattern verification and parametric testing at full-wafer parallel test, the FOX-1P system provides a highly differentiated solution from competitive alternatives for microcontroller test, flash wafer test, embedded memory or any wafer with long test times. These capabilities are particularly well suited for automotive applications where test and burn-in for early failure screening of devices is vital.

The FOX-1P is integrated with a high performance dual wafer probing platform developed by Semics, Inc. that incorporates two FOX-1P test systems in an industry leading small footprint for a high performance full featured wafer prober.

The FOX-P product family also includes multi-wafer FOX-XP test solutions that utilize the same Universal Channel technology. The FOX-XP systems are capable of functional test and burn-in/cycling of flash memories, microcontrollers, sensors, optical devices, laser diodes, VCSELs, LEDs and other leading edge ICs in wafer form before they are assembled into multi-die stacked packages or other applications where known good die are critical. These end applications can span enterprise solid state drives, automotive devices, highly valuable mobile applications, communications and mission critical integrated circuits and sensors.

The multi-wafer FOX-XP system utilizes the FOX-1P Channel Module to provide up to 2,048 Universal Channels per wafer, allowing the system to test all the devices on each wafer in parallel. This enhanced architecture allows customers to perform per pin parametric testing, more extensive digital pattern test with deeper data stimulus / capture memory (32M per pin), and deeper scan (768M) optimized for BIST/DFT testing. The multi-wafer FOX-XP system utilizes Aehr Test’s FOX WaferPak contactor, which provides a cost effective solution for making electrical contact with a full wafer or substrate in a multi-wafer environment which can be scaled to simultaneously test up to 54 wafers in a single test cell.
