Icepak–Mechanical coupled thermal-flow and stress analysis for electronics
Ansys, part of Synopsys · Thermo-mechanical simulation and lifetime prediction
- Purpose
- Cooling conditions change package, board and system temperatures, affecting thermal expansion, displacement and stress.
- Technical approach
- Icepak models conduction, convection and radiation. The 2024 R2 tutorial imports steady-state temperatures into an AEDT Mechanical–Structural design to calculate stress and displacement.
- Scope of use
- Supports cooling comparisons for packages, boards, heat sinks and enclosures, followed by structural assessment. Package-warpage and lifetime studies require suitable models and tools.
- 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 limitationsThis tutorial demonstrates one-way transfer, not universal two-way coupling or fatigue-life capability. Materials, contacts, supports and process assumptions affect results.
What to prepareBLNKK suggests preparing geometry and stack-up, power, cooling boundaries, material properties, contacts and supports, plus measured temperatures and deformation for comparison.
Confirm with the supplierConfirm versions and licenses, the AEDT or other Mechanical workflow, temperature mapping, and tools required for nonlinear materials, residual stress or life prediction.
- Public evidence
- The current product page describes chip-to-system thermal/structural analysis. The versioned power-resistor tutorial demonstrates temperature transfer and constrained structural response.
