Aehr Test Systems (AEHR)

Aehr is best known for solutions that test and burn in devices at wafer level, die level, and package level. Burn-in is a reliability process that stresses chips under controlled conditions to screen out early failures. This capability is increasingly important as semiconductors are used in applications where performance and durability are critical, including electric vehicles, automotive power electronics, mobility systems, data infrastructure, optical devices, memory, and logic products.

The company’s product families include ABTS and FOX systems, along with related tools and consumables such as the FOX WaferPak Aligner, FOX-XP WaferPak Contactor, FOX DiePak Carrier, and FOX DiePak Loader. These products support different stages of the production flow and are intended to help customers improve yield, reduce field failures, and qualify devices for high-reliability uses.

Aehr has gained particular market attention because of its exposure to silicon carbide and other advanced semiconductor technologies used in electrification and power conversion. As chip designs become more complex and end-use requirements become stricter, manufacturers often need more sophisticated test strategies. Aehr’s niche is providing equipment that can test many devices efficiently while supporting the reliability standards required by automotive, industrial, and communications markets.
