Board-Level Thermal Choices Become System-Level Constraints
Placement, copper distribution, spacing, and via strategy determine local hotspots and set the boundary conditions every enclosure and system design has to live with.
Why thermal decides the outcome here
A board layout that looks clean electrically can create a thermal bottleneck that no enclosure design can recover from cheaply. Thermal review at the ECAD stage — not after fabrication — is what keeps rework off the schedule.
Engineering Challenges
- Component placement and thermal coupling between neighbors
- Copper distribution and plane spreading capacity
- Airflow assumptions carried from board to enclosure
- Heat sink and via-strategy sizing
- Prototype-to-simulation mismatch
- TIM bond-line consistency across the build
Dominant Thermal Physics
- Copper-plane spreading resistance
- Component-to-component conductive and radiative coupling
- Local convection along the board surface
- Via-array thermal conduction
- TIM bond-line thickness and pressure dependence
Applicable Standards
- IPC-2221 thermal derating
- IPC-2152 current-carrying capacity
- JEDEC JESD51 board-level test conditions
