Abstract As we entered the current century, consumer electronics were primarily cooled using aluminum. Over the last 15 years, flexible graphite heat spreaders have largely replaced aluminum for thermal management in many advanced consumer electronics devices where properties of being thin or lightweight are desired. There are two types of flexible graphite, natural and … [Read more...]
Thermal Interactions between High-power Packages and Heat Sinks, Part 2
Calculation Corner Bruce Guenin, Assoc. Technical Editor Introduction These days, many thermal engineers face the challenge of defining effective heat sink cooling solutions for high power processors and ASICs (Application-Specific Integrated Circuits). The usual practice would be to calculate a value of ΘJA (junction-to-air thermal resistance) for the … [Read more...]

Heat Spreader Efficiency Improvements by Addition of Latent Heat Solution Materials
Introduction Electronics thermal management has become an increasingly important design focus as devices have become more constrained, more powerful, more expensive and more ubiquitous. To manage temperatures, particularly in mobile devices, thermal engineers typically use higher thermal conductivity components and materials. Electrical engineers strive to spatially … [Read more...]
Summary of the IEEE ITherm 2019 Conference
Technical Brief John F. Maddox, Ph.D., P.E.
