Introduction 1 Introduction 1.1 Document Goals and Scope 1.1.1 Importance of Thermal Management The objective of thermal management is to ensure that the temperatures of all components in a system are maintained within their functional temperature range. Within this temperature range, a component is expected to meet its specified performance. Operation outside the functional temperature range can degrade system performance, cause logic errors or cause component and/or system dama

The die-side capacitors, which are only slightly shorter than the die height, are electrically conductive and contact with electrically conductive materials should be avoided. The use of an insulating material between the capacitors and any thermal and mechanical solution should be considered to pr

The higher the air velocity over A the surface, and the cooler the air, the more efficient is the resulting cooling. The nature of the airflow can also enhance heat transfer via convection. Turbulent flow can provide improvement over laminar flow. In the case of a heatsink, the surface exposed to the flow includes in particular the fin faces and the heatsink base. Active heatsinks typi
