TCC 20 K/min rapid-rate thermal cycling for interconnect fatigue
ESPEC · Reliability qualification and failure analysis
- Purpose
- Repeated temperature cycling can accumulate fatigue in package and board-level joints as materials expand at different rates. Evaluation needs a traceable specimen-temperature history.
- Technical approach
- TCC controls heating and cooling ramps within one chamber. The TCC-151W-20 specification includes specimen-temperature ramp control, combined with programmed temperature levels and dwell periods.
- Scope of use
- It is an equipment option for thermal cycling of semiconductor packages, automotive electronics and board assemblies. Whether a profile reproduces the relevant joint stress and failure mode requires a specimen-specific test plan.
- 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 limitationsThe 20 K/min rating is conditional on model and reference loading; it does not establish that rate throughout the operating range or at every internal package location. The chamber alone does not establish joint failure or fatigue life.
What to prepareBLNKK suggests preparing specimen quantity and geometry, fixture/loading details, the target profile, sensor locations and failure criteria, including any need for resistance monitoring or post-test analysis.
Confirm with the supplierConfirm the model, applicable standard edition, achieved specimen profile under the proposed load, and the scope of wiring, monitoring equipment and reporting.
- Public evidence
- ESPEC’s 2025 announcement specifies a 20 K/min specimen ramp with 5 kg of glass-epoxy boards and a 4 kg jig; the TCC catalog supplies model-specific test intervals and configurations.
