Aehr Test Systems says a supplier of AI accelerators, CPUs and network processors has decided to buy a FOX-XP wafer-level burn-in test cell for evaluation at an outsourced semiconductor assembly and test partner in Taiwan. Installation is planned for early 2027, following a benchmark completed with the customer during the previous quarter. [1]
The next evaluation will use the same device in a high-volume production environment, with a decision on wider production expected several months after installation and validation. Aehr has not named the customer or disclosed the planned cell’s detailed configuration. [1]
The FOX-XP platform uses WaferPak contactors to connect test resources to a full wafer before it is cut into individual dies. Aehr describes configurable resources for functional testing and burn-in, with voltage and current protection at individual channels, allowing devices to operate while they undergo the selected reliability stress.

Wafer handling forms part of the system. An automatic aligner loads wafers into the contactors and shares wafer identity and test-program information with the FOX-XP. Those functions connect the electrical test to the loading and tracking of wafers through the equipment, providing the surrounding production workflow for the evaluation planned in Taiwan. [2]
