About Us

Aehr Test Systems

Headquartered in Fremont, California, Aehr Test Systems is a worldwide provider of test systems for burning-in and testing logic, optical and memory integrated circuits and has over 2,500 systems installed worldwide. Increased quality and reliability needs of the Automotive and Mobility integrated circuit markets are driving additional test requirements, incremental capacity needs, and new opportunities for Aehr Test products in package, wafer level, and singulated die/module level test.

Aehr Test has developed and introduced several innovative products, including the Tahoe and Sonoma systems and FOX-P families of test and burn-in systems and FOX WaferPak Aligner, FOX WaferPak Contactor, FOX DiePak Carrier and FOX DiePak Loader. The Tahoe and Sonoma systems are used in production and qualification testing of packaged parts for lower power and higher power logic devices as well as all common types of memory devices. The FOX-XP system is a full wafer contact and singulated die/module test and burn-in system used for burn-in and functional test of complex devices, such as leading-edge memories, digital signal processors, microprocessors, microcontrollers, systems-on-a-chip, and integrated optical devices. The WaferPak Contactor contains a unique full wafer probe card capable of testing wafers up to 300mm that enables IC manufacturers to perform test and burn-in of full wafers on Aehr Test FOX systems. The DiePak Carrier is a custom designed reusable test board for the FOX-XP system which enables IC manufacturers to perform cost-effective test/burn-in of singulated die and modules.

Aehr Test Systems’ corporate headquarters has been certified to the International Standards Organization (ISO) 9001 standard since 1997.
