Introduction The electronic industry requires increased forced-air cooling limits to cool high-end server CPUs adequately. Improving air-cooled heat sink thermal performance is one of the critical areas for increasing the overall air-cooling limit. One of the challenging aspects for improving heat sink performance is the effective utilization of relatively large air-cooled fin … [Read more...]
Entrance Effects For Heat Flow Into A Multi-Layer Printed Circuit Board
Introduction Since their introduction, multilayer printed circuit boards have provided a significant benefit to the thermal management of IC packages. As is widely recognized, the power and ground planes in these boards function as fins and spread the heat beyond the package footprint and enhance heat transfer to the air. Heat can flow into these planes by conduction either … [Read more...]
Thermal design of fault tolerant and high availability computer systems
Thermal Design is one of the most challenging aspects of computer system design. This is definitely the case when it comes to designing for “fault tolerance” and “high availability” in high-speed multiprocessor-based systems. The inherent challenges associated with fault tolerance not only bring demanding design requirements but headaches as well. The term fault tolerance … [Read more...]
DELPHI – A status report on the European -union funded project for the creation and validation of thermal models on electronic parts
The accurate prediction of the operating temperatures of critical electronicparts at the component-, board- and system-level is seriously hampered by thelack of reliable, standardised input data. The DELPHI project is addressing thisproblem by the development and experimental validation of thermal models of avariety of `generic' electronic parts. DELPHI (which stands for … [Read more...]
