The article discusses the importance of thermal evaluation of integrated circuits to ensure system reliability. Measuring thermal response with this type of board proves that the rise in temperature under full-load conditions of the dual low-dropout increases from 32°C (four-layer with vias) to 59°C. Under these conditions, the maximum ambient temperature is (125°C--59°C), or 66°C. This temperature difference is primarily due to lack of internal layers and vias directly into the copper plane, as the JEDEC standard defines. Thus, although data-sheet specifications are accurate, the physical implementation of the product on the pc board weakens the device's thermal performance.
