In the last decade, we've come a long way in the application of thermal analysis to the design of electronics. And there's no sign of the pace of innovation changing. Engineers are still being challenged to build faster, smaller and cheaper products in ever-decreasing design times. Fortunately, the engineering software industry has been able to respond by providing tools that … [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...]
Electronic package characterization per JEDEC standard
Introduction With the increase in power density resulting from advancements insemiconductor packaging technologies comes the issue of heat dissipation. Heatis generated as a result of electrical energy being converted to thermal energyduring circuit activities. The junction temperature of a chip directly affectsthe performance of the circuits and the reliability of … [Read more...]
Applying computational fluid dynamics to heat sink design and selection
Abstract This article describes how Computational Fluid Dynamics (CFD) can help inthe selection and/or design of a heat sink for electronics cooling applications.CFD modeling complements the other tools in the thermal tool kit: calculationsbased on approximations and correlations; and experimental work. Whether theapplication includes single or multiple heat sinks, the … [Read more...]
Safety tips and techniques for FEA in modeling solids
Using commercially available finite element analysis (FEA) software is easier today than it has ever been. Software vendors have made great progress toward providing programs that are as easy to use as they are powerful. But, in doing so, software suppliers have created a perilous quagmire for unwary users. Some engineers and managers look upon commercially available FEA … [Read more...]
