Examples of state-of-the-art thermal management solutions at the dawn of the 21st century (left to right): a TCM module, a high-density heat sink, and an ultra performance, low profile fan-sink. Thermal management has served as a key enabling technology in the development of advanced microelectronic systems and has facilitated many of the "Moore's Law" [Moore, G.E., 1975] … [Read more...]
Improving productivity in electronic packaging with flow network modeling (fnm)
As the complexity and power density of electronics systems increase, so too does the demand for tools to improve both product quality and designer productivity. This is especially true for thermal designers who use Computational Fluid Dynamics (CFD) tools for thermal designs. Several important factors are driving this trend: System complexity has increased to the point that … [Read more...]
