Almost every week manufacturers present yet another component that has been reduced in size by 30% to 50% while maintaining similar performance characteristics. The size and weight requirements of the notebook and sub-notebook computer market have resulted in the development of increasingly smaller components. These consumer products have placed very stringent requirements on size, weight and run time. Because of component density, heat dissipation has also become one of the highest concerns ...
