ETS-88 power-device and module electrical comparison

Teradyne · Geometric and electrical metrology

Purpose: Compare electrical parameters before and after power cycling to assess device/module changes.
Technical approach: Independent floating resources per site and configured voltage/current instruments execute test programs.
Scope of use: Teradyne lists SiC/GaN, discrete devices and power modules; accessible terminals and configuration-compatible operating points are needed.
Limitations and open questions: These evaluation considerations are compiled by BLNKK from public information. They are not supplier guarantees or a mandatory submission checklist.
Scope and limitations
The page does not establish complete power cycling or online thermal-resistance measurement. Parameter drift alone cannot locate clip/die-attach damage.
What to prepare
BLNKK suggests preparing cycle history, operating points, temperature, terminals, baseline parameters, fixture parasitics and Kelvin paths.
Confirm with the supplier
Confirm instruments, safe voltage/current ranges, protection, fixtures, thermal control, calibration and before/after correlation.
Public evidence: The ETS-88 page documents applications, floating resources, test-head configurations and instrument options.
