This time I found it difficult to find a suitable subject for my editorial. My original idea was to write about heat spreading, again. I found some interesting facts pointing at problems of interpretation for dual layers when using the often-used heat spreading equations while writing a white paper on basic thermal management for LED applications for this year’s APEX/IPC … [Read more...]

There must be an ideal world A sort of mathematicians’ paradise Where everything happens As it does in textbooks — Bertrand Russell This is the third column devoted to the sense and nonsense of correlations. My earlier comments [1] regarding Russell’s quote are maybe worth repeating: “Generations of mechanical engineers have been educated to use the correlations that fill … [Read more...]

Microelectronics and microsystems play a vital and increasingly important role in current and future human life and society. The future will bring a plethora of new products/processes based on new concepts with limited past experience to build upon. Much of the research of microstructures involves thermal management in one way or another, such as in relation to the biochemistry … [Read more...]
