Statistical analysis is needed because data always have some degree of uncertainty; a value that we determine from a single measurement, or even set of measurements, is not necessarily going to tell us exactly what value we will determine with additional measurements. Statistical analysis uses the mathematics of probability to create tools that we can use to deal with … [Read more...]
Heat Transfer and Pressure Drop Correlations for Manifold Microchannel Heat Sinks
Written by: Sevket U. Yuruker, Raphael K. Mandel, Amir Shooshtari and Michael M. Ohadi - Department of Mechanical Engineering, University of Maryland Conventional microchannel cooling has been proven capable of removing high heat fluxes, but usually at significant pressure drops. On the other hand, manifold microchannel systems offer high heat transfer coefficients/heat … [Read more...]
Electrically Conductive Die Attach Adhesive Has Very High Thermal Conductivity
In this video demonstration, learn more about EP3HTSDA-1, a thermally conductive die attach epoxy, and see how easily it dispenses. One component Master Bond EP3HTSDA-1 is formulated primarily for die attach applications. It exhibits a die shear strength of 20-22 kg-f and has a high thermal conductivity of 40-45 BTU•in/ft2•hr•°F [5.7-6.5 W/(m•K)]. “This 100% solids … [Read more...]
Statistic Corner: Comparing Populations
Introduction Previous articles in this series described the normal distribution and how it is used to relate probability and confidence levels [1, 2]. A practical application of the use of the confidence interval was to describe how to determine the range of values in which the true mean of a population falls within, based on the mean and standard deviation calculated from a … [Read more...]
Future Trends in LED Driver System Modeling
Introduction A decade ago, the major players in the lighting industry decided to make the transition to digital systems and set the pace in connected lighting. At present, only a few companies can maintain their leadership. As a self-fulfilling prophecy, the lighting landscape changed remarkably, with scattered competitors having access to internet of things (IoT) ecosystems … [Read more...]
