Systematic thermal solutions also need universal design regulations and thermal testing standards. These challenges have involved all electronic market segments. For instance, the mobile processor market segment is typically constrained by battery life ($2–3 h), and the form-factor must be small and light to allow for portability. If the desktop market is more cost sensitive, the mobile market is more space and weight sensitive. These sensitivities place boundariess on the effective power removal capabilities of the electronic package.

2008). 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.

There have been many approaches for optimal thermal design to reduce the thermal resistance and maximize the intrinsic performance and lifespan of semiconductor devices, helping meet market needs for higher performance as well as saving costs by curtailing the need for heat dissipation measures. For example, the thermal resistance of QFPs (quad flat packages) can be reduced through appropriate material selection and lead frame design (NEC Electronics 2003): (1) Employment 26 1 Thermal Management Fundamentals and Design Guides in Electronic Packaging of thermally enhanced resin.
