This article presents an overview of a number of dynamic measurement methods as part of the European PROFIT project. Due to lack of space, details cannot be given, but the interested reader is invited to consult the references at the end of the article. Because the majority of a product's cost and performance are committed in the early phases of a design cycle, it is envisioned … [Read more...]
Diamonds are a Thermal Designer's Best Friends
Different forms of carbon, such as processed natural graphite, pyrolytic graphite, diamond-like carbon, and synthetic diamond, offer lots of possibilities for maximizing conductive heat transfer.Synthetic diamond has already found its place as a common solution for heat spreaders inside semiconductor laser components, where temperature stabilization is of utmost importance for … [Read more...]
Advanced Techniques for IC Surface Temperature Measurement
Introduction: The Need for IC Surface Measurement Techniques Current trends in microelectronic design generate challenges in both the design and test of integrated circuits (ICs). One area that has been gaining increased relevance with regard to the microelectronic evolution is thermal management/analysis, which proves essential in the domain of IC design to prevent reliability … [Read more...]
Thermal Issues in GaAs Analog RF Devices
Wireless communication and advanced radar systems require circuitry that can operate at frequencies greater than 2 GHz and at high power levels. Analog gallium arsenide (GaAs) semiconductors are frequently used in these applications and present additional challenges for thermal engineers compared to silicon semiconductors. Whereas thermal characterization modeling and … [Read more...]
Thermal I/O
Don't do a spit-take with your coffee - there is no double-sided BGA. It would never see the light of day, simply because no one would ever buy it. Sure the density is unbeatable, but there is no practical method of soldering all the leads on such a package to a printed circuit board. No electrical hardware design engineer would accept such a ridiculous package. Then why do … [Read more...]
