Aehr Test Systems Receives $6 Million Order for a FOX-15™ Multi-Wafer Burn-In
System for Production Test & Burn-In Application
Fremont, CA (April 27, 2015) - Aehr Test Systems (NASDAQ: AEHR), a worldwide supplier of
semiconductor test and burn-in equipment, today announced it has received an order from a new
customer for a FOX-15 Multi-Wafer Test and Burn-In System, multiple WaferPak™ contactors and a
WaferPak Aligner. The order is for more than $6 million and is for a production test and burn-in
application. The order includes prepayments in order to lock in lead times and volume-related discounts
and is expected to ship within the next six months.
“We are very excited to announce our initial order from this major new customer,” said Gayn Erickson,
President and CEO of Aehr Test Systems. “This production customer is extremely quality and cost
conscious, which makes them a great match for the reliability and yield improvements that our wafer level
burn-in and test solutions provide.”
“We see the markets for automotive sensors and infotainment, mobile consumer electronic devices,
servers with high-reliability stacked flash memory, and ultimately the Internet of Things (IoT), as key
growth opportunities for Aehr Test’s wafer level test and burn-in solutions,” said Carl Buck, Aehr Test Vice
President of Marketing. “Aehr Test currently has an installed base of customers using our FOX-15 multiwafer
test systems in the automotive sensor and data communications spaces with systems configured to
test and burn-in 15 wafers in parallel in high volume production today. This new customer’s production
application represents a significant opportunity for Aehr Test as we expand our unique and highly cost
effective wafer level test and burn-in solution into the rapidly growing automotive, consumer, mobile, and
computing markets.”
Buck continued, “Extensive test and burn-in is required to weed out early-life failures to meet the
standards of automotive and quality conscious consumer, server, and mobile device manufacturers. The
challenge is how to handle these devices, which are often extremely small, measuring in the one to few
millimeters in size and having thousands or even tens of thousands of devices per wafer. Contacting the
devices in package form is often both impractical and expensive. Aehr Test provides a unique solution to
contact and test all of the devices at once in wafer form. Today, we test wafers with up to 20,000 devices
at a time and can do this at elevated temperatures up to 170C with our proprietary WaferPak contactors.
Typical packaged part burn-in systems can only go to 150C and typical wafer probe cards used in
production today may only go up to 125C. Aehr Test can make contact with the very small contact pads
that are often under 100 microns wide (less than four one-thousandths of an inch) and 200 microns apart
from each other versus typical pads on surface mount package parts with 300 microns wide pads that are
1,000 microns apart. Our customers have shown that handling and burning-in their devices in wafer form
is much more reliable and leads to higher quality and lower defect rates in the end products. Our FOX-15
multi-wafer burn-in system can burn-in 15 wafers at once, allowing customers to test thousands of
devices on each of the 15 wafers in parallel, providing them with a very low cost platform for doing test
and burn-in of their wafers.”
Aehr Test’s FOX family of products is focused on high reliability test needs and long-duration full wafer
burn-in and test of products such as sensors, automotive ICs, discrete memories, and devices with
embedded memories including microcontrollers and smart card devices. The FOX-1 system offers highthroughput
single-touchdown sort testing. The FOX-15 system has a capacity of up to 15 WaferPak
single-touchdown full wafer contactors for burn-in and test of state-of-the-art integrated circuits and
sensors. Testing the ICs in wafer form before they are assembled into multi- die stacked packages
enables the stacked packages to then be used for high reliability and quality applications such as
enterprise solid state drives, automotive devices, mission critical integrated circuits and sensors. Aehr
Test’s recently-introduced FOX-1P system extends the capabilities of its FOX-1 system by adding high
density, low cost I/O and DPS modules with the capability to provide over 16,000 I/O or DPS channels in
a single test head for massive parallelism on a single wafer.
About Aehr Test Systems
Headquartered in Fremont, California, Aehr Test Systems is a worldwide provider of test systems for
burning-in and testing logic and memory integrated circuits and has an installed base of more than 2,500
systems worldwide. Increased quality and reliability needs of the Automotive and Mobility integrated
circuit markets are driving additional test requirements, capacity needs and opportunities for Aehr Test
products in package and wafer level test. Aehr Test has developed and introduced several innovative
products, including the ABTSTM and FOX families of test and burn-in systems and the DiePak® carrier.
The ABTS system is used in production and qualification testing of packaged parts for both low-power
and high-power logic as well as all common types of memory devices. The FOX system is a full wafer
contact test and burn-in system used for burn-in and functional test of complex devices, such as leadingedge
memories, digital signal processors, microprocessors, microcontrollers and systems-on-a-chip. The
DiePak carrier is a reusable, temporary package that enables IC manufacturers to perform cost-effective
final test and burn-in of bare die. For more information, please visit Aehr Test’s website at www.aehr.com.
