Figure 1. Transistor counts on Intel processors from inception to present superimposed on Moore's prediction. In his fascinating book, "Visions," Michio Kaku [1] predicts a future driven by silicon and quantum computers. Based on the information we have today, it is intriguing to speculate how such a highly silicon-based society might function and evolve. Being a thermal … [Read more...]
Ten stupid things engineers do to mess up their cooling
Editor's Note: On the eve of the new millenium, the editors of ElectronicsCooling have decided to depart from our normal serious tone just this once, unless, of course, we can convince Tony to contribute another story or two for us sometime [soon!] in the next thousand years. Herewith, for your amusement and edification is a humorous, yet insightful, retrospective of famous - … [Read more...]
Computer-related thermal packaging at the millenial divide
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...]
Determining the junction temperature in a plastic semiconductor package, part II
In the majority of applications involving plastic surface-mount packages, most of the heat generated by integrated circuits will flow to the printed circuit board (PCB) by way of the package leads and then to In higher-power applications it is often necessary to attach a heat sink to the top of the package to keep the junction temperature of the chip within specified limits. … [Read more...]
Design and reliability considerations in avionics electronics packaging
In the avionics industry, regulatory agencies and standards organizations, such as Federal Aviation Regulation (FAR) [1], Aeronautical Radio, Inc. (ARINC) [2], and Radio Technical Commission for Aeronautics (RTCA) [3], have developed sets of test procedures that help design engineers test and verify their designs and prevent any safety-threatening failures. Too often, however, … [Read more...]
