BLNKK's current understanding
Please check the details- Package architecture
- Multi-die package / heat spreader or lid-to-heatsink interface
- Observation
- Local hotspots and suspected uneven contact; heat-source power distribution unconfirmed
- Evaluation stage
- Thermal assembly and steady-state measurements; not a power-cycling lifetime issue
- Variables to validate
- TIM thickness, pressure, surface topography, and heat-source distribution
- Missing information
- TIM1 / TIM2 location, power and temperature maps, bond-line thickness, and clamping
Paths to assess first
