ElectronicsCooling magazine was founded more than 12 years ago with a mission of providing current and practical thermal management information with archival value. I hope you agree this magazine is still delivering on its original promise. The last word in the mission statement is value, and each of us, as a thermal engineer, desires to add value to our projects. Admittedly, … [Read more...]
Packaging Challenges For High Heat Flux Devices
Introduction It comes as no surprise to anyone in our industry that device power levels are increasing to support customer expectations of ever greater functionality and performance. The greatest thermal challenges in computing occur in the packaging of processors. This results not only from the fact that processors typically have the largest overall power dissipation in a … [Read more...]
So Many Chips, So Little Time; Device Temperature Prediction in Multi-Chip Packages
Introduction The same trend that has led to ever-higher levels of integration of computation and processing functions on a single chip is now driving the integration of several chips into the same package. The use of multi-chip packages (MCPs) enables miniaturization of a circuit when it is not practical to incorporate all of the desired functionality on a single chip. The … [Read more...]
Use of junction-to-board thermal resistance in predictive engineering
The readers of "Electronics Cooling" are familiar with the reasons why the junction to ambient thermal resistance [1], JA or RJA, is an inadequate description of the thermal performance of an integrated circuit. Likewise, you realize that vendors cannot continue to state the integrated circuit will work at a specified ambient temperature (55°C, 70°C, 85°C, or 125°C) as device … [Read more...]
