Aehr Test Systems (AEHR) and Cohu, Inc. (COHU) both operate in the semiconductor industry but offer different product lines: Aehr Test Systems (AEHR) - Specializes in wafer-level burn-in semiconductor testing
3
. - Primary products include the FOX-P series testers, which require WaferPak Contactors and WaferPak Aligners for full test process automation
3
. - Offers FOX-XP and FOX-NP systems for full wafer contact and singulated die/module test and burn-in
4
. - Recently expanded into AI processor testing with wafer-level burn-in solutions capable of delivering thousands of watts of power per wafer at temperatures up to 150 degrees Celsius
7
. - Unique in offering both wafer-level and package-level turnkey test and burn-in solutions for AI processors
7
.
Cohu, Inc. (COHU) While specific product details for Cohu are not provided in the search results, we can infer the following based on industry knowledge: - Cohu is generally known for providing a broader range of semiconductor test and inspection equipment.
- Their product line typically includes handlers, test contactors, and inspection systems for semiconductor devices.
- Unlike Aehr's focus on wafer-level testing, Cohu's products are often used for testing packaged semiconductors.
The key difference is that Aehr focuses on wafer-level burn-in and test solutions, particularly for power semiconductors and now AI processors, while Cohu offers a wider range of semiconductor test and inspection equipment, likely at the packaged device level.
