To calculate junction temperature, identify heat sources and compute worst-case power dissipation, then apply thermal resistance metrics to verify safe operating limits for components like LDOs, DC-DCs, and MCUs.

Preventing PCB overheating requires evaluating thermal performance early and prescribing mitigation steps such as thermal vias, copper pours, and via arrays to manage heat across rigid and flex substrates.

Designing thermal vias and copper pours involves creating thermal relief structures and via arrays tailored to the power dissipation of RF stages and LEDs, ensuring the board meets safe operating temperature limits.

Yes, thermal analysis applies to both flex and rigid substrates across consumer, industrial, and automotive contexts, providing a step-by-step workflow to manage heat in battery-powered devices and other compact assemblies.

While theta-ja evaluates junction temperature, high-density designs often require additional mitigation structures like via arrays and copper pours because standard metrics may not capture complex thermal coupling in compact assemblies.

Overheating despite thermal vias indicates the need to evaluate the complete thermal design workflow, computing worst-case power dissipation and verifying the via arrays and copper pours meet the MCU's safe operating limits.
