A simple formula to estimate the natural convection heat transfer coefficient on a flat plate was presented in a preceding column [1]. If, instead of a single plate, we wish to consider a closely spaced array of vertically oriented parallel flat plates, a different formula is required. The geometry to be considered appears in Figure 1 and is typical of that for a vertically … [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...]
