SOLUTION NAVIGATOREngineering conditions
For “Device functional, burn-in and stress-test failures”, add details that may change the assessment order and check the basis and limits of each candidate.
Engineering conditions
Check the failure mode, test coverage, contact and actual device temperature before preparing reproducible functional tests and fault localization. Unknown conditions remain pending; readiness does not qualify a solution or establish a root cause.

The order changes only with conditions you confirm. Public information cannot establish suitability for your actual samples.
After a controlled comparison, use the observed result to plan the next step.
A trend, recovery or correlation cannot establish root cause, exclude other failures or guarantee production results.
Based on reported conditions and public sources. Ready to assess does not establish sample applicability or root cause. Order does not identify the best solution.

Aehr Test Systems · FOX-XP wafer, bare-die and module burn-in and test ↗Scope and limitations System power, contactor capacity and channel maxima should not be assumed to apply simultaneously to one configuration. Burn-in can expose or screen electrical failures, but does not independently identify a physical root cause or guarantee reliability or yield. What to prepare BLNKK suggests preparing DUT form, pins and contact carrier, test patterns or BIST, failure criteria, electrical baselines, bias/current/temperature/duration profiles and checks for contact or stress errors. Confirm with the supplier Confirm DUT/contactor compatibility, test coverage and electrical resources, power configuration and how actual junction temperature is measured. Also confirm failure logging, contact checks and whether optional automatic alignment is needed.
Cohu · T-Core active thermal control for high-power IC test ↗Scope and limitations Heater or head readings are not necessarily junction temperature, and a 1 ms control loop does not establish a 1 ms junction-temperature settling time. Power, ramp and temperature ratings depend on the head, interface and configuration; they are not package-reliability guarantees. What to prepare BLNKK suggests preparing device/package dimensions, transient power profiles, available temperature feedback, socket/head contact and interface materials, setpoints and tolerances, plus calibrated reference temperatures and electrical results. Confirm with the supplier Confirm head/handler/tester compatibility, junction-temperature measurement or estimation, steady-state and transient acceptance conditions, contact/socket force, and the selected configuration’s power and temperature limits.

The actual powered test/burn-in system supports recording electrical failure/drift under controlled stress; fixture validity and device stress must be established independently.
Basis: The page and FOX-XP Rev C brief list up to 18 WaferPak or nine DiePak blades and system capacity up to 3500 W per wafer. The page separately lists WaferPak contactor capacity up to 2 kW; these ratings require configuration-specific confirmation.Cohu
Active thermal control helps distinguish genuine electrical failure from an unintended junction-temperature excursion, but is only the temperature-control part of the test.
Basis: The current page lists power management up to 800 W, a 1 ms control loop and ramps up to 100°C/s. The REV20200530 sheet specifies ±1°C accuracy at the heater; a September 2025 Eclipse announcement separately reports up to 3 kW for that platform context.AEM Holdings
Controlled burn-in stress and device-specific thermal management support screening comparisons, not power-cycle Rth characterization.
Basis: The website and AMPS-BI brochure document parallel electrical stress, multi-zone thermal control and individual-device operation. They do not qualify screening coverage, junction temperature or complete reliability for a customer product.Chroma ATE
Engineering SLT verifies workload, contact and thermal conditions before production transfer; defect coverage still needs validation.
Basis: Chroma’s 2025/2026 announcements distinguish 3210-A engineering validation, 3200 production configurations and the transfer workflow.Teradyne
Configured patterns and DFT visibility can reproduce electrical failures; ATE is not automatically burn-in or interface imaging.

Limit: Scope and limitations Burn-in screening is not full reliability qualification or direct measurement of power-cycling thermal-resistance degradation. Maximum power, current and channel counts are not necessarily simultaneous; confirm how controlled temperature relates to junction temperature. What to prepare BLNKK recommends preparing package dimensions, socket/contact needs, test programs, power variation and target stress duration. Include temperature references, screening coverage and failure criteria to plan configuration validation. Confirm with the supplier Confirm simultaneous device count, per-device power/current/channel configuration and temperature-control location.

What to prepare BLNKK suggests preparing test programs, DFT observability, power and interface needs, DIB and contact information, temperature conditions and failure records.
