Clemens J.M. Lasance Guest Editor, Philips Research Emeritus, Consultant at SomelikeitCool I assume everybody agrees with the fact that it is pointless to devote precious space in this magazine to highlight again all problems related to thermal management of electronic products and systems, so let’s start right away. An important way of reducing the temperature in an optimal … [Read more...]
Happy 25th Birthday FloTHERM !
Late in 1988 two key employees of CHAM (Concentration Heat And Momentum Ltd.), the first commercial CFD vendor and at the time market leader, left to set up a new type of CFD company. Recognising the opportunity to package CFD in focussed, highly automated and application specific products, David Tatchell and Harvey Rosten started to develop what would become FloTHERM. A CFD … [Read more...]
Editorial – Getting Back to Basics
As a young engineer in the 1990s, I considered Electronics Cooling magazine as one of the first ports of call as a reference source when venturing into a new area of electronics thermal design. When I was invited to join Electronics Cooling’s editorial team, I re-read the first editorial by Kaveh Azar [1]. He outlined the need at that time (1995) for a publication vehicle that … [Read more...]
Testing of Power LEDs: The Latest Thermal Testing Standards from JEDEC
András Poppe, Ph.D.; Mentor Graphics MAD MicReD Unit The electrical, thermal and optical parameters determining light emitting didoes (LEDs) operation are in a strong, mutual dependence; without knowledge about the parameters in one of these domains the other characteristics cannot be measured correctly. The reliability, useful operating life time and luminous flux are … [Read more...]
Thin Film Thermal Conductivity Measurement using a Micropipette Thermocouple
R. Shrestha, K. M. Lee and T. Y. Choi - University of North Texas D. S. Kim - POSTECH INTRODUCTION Due to the required experimental characterization complexity for the thermal conductivity measurement of thin films, accurate measurement of such materials has been difficult to achieve for thicknesses less than 1 µm. For example, conventional Fourier heater plate … [Read more...]
