As the package level goes from the chip die to its packaging, to a board, to a motherboard, to a system, the area over which the heat is distributed increases so the heat flux decreases correspondingly. This allows heat removal at one or more packaging levels, where the heat flux and temperature differences are consistent with the available cooling method (Couvillion 2006). 4, such hardware typically consists of the use of natural convection, forced convection, fluid-phase change, thermionic and liquid cooling devices, as well as interface materials, mounting assembly, allocated system, and component and motherboard placement.

This would build up a new routine for future system-level thermal management of electronic packaging. Thermal Management Solutions Effective thermal management of an electronic system requires identifying critical issues such as shock, vibration, and usage scenarios, considering potential coupling effects, and developing an integrated, interdisciplinary solution (Madrid 2000). This usually can be achieved based on understanding the thermal behavior of a system and optimizing that behavior for cost efficiency through modeling and analyzing the system, including for instance (1) system-level cooling and active control; (2) board-level and chip-level thermal design and thermal management; (3) device or die electrothermal modeling and optimal thermal design; and (4) microor nanoscale thermal design and engineering or processing.
