PCT3 calibrated power-cycling monitoring
SCHLETZ GmbH · Reliability qualification and failure analysis
- Purpose
- Comparing thermal-resistance and electrical drift during power cycling requires consistent measurement timing and cooling conditions.
- Technical approach
- PCT3 heats devices through their own losses, combining cooling, indirect junction-temperature measurement and temperature/voltage calibration with heating/cooling logs.
- Scope of use
- Fixed-current and fixed-temperature-swing strategies are described. Match device control, timing and cold-plate configuration to the project.
- 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 limitationsRth drift alone cannot locate an internal failure layer or establish every product’s field life.
What to prepareBLNKK suggests device connections, temperature swing, on/off times, cooling/clamping conditions, baseline traces and stopping criteria.
Confirm with the supplierConfirm configuration limits, junction calibration, timing delays, Rth method, processing options and exported data.
- Public evidence
- The technical body describes cycle-by-cycle records, Rth calculation and time-dependent calibration; some impedance post-processing and cold-plate features are optional.
