INTRODUCTION The state of the art in performing thermal calculations in our industry is very advanced. However, how applicable the results of a calculation are to the real-world performance of a packaging or an active cooling component depends on the quality of the data characterizing these various components. In the real world of manufacturing, such characterization … [Read more...]
Beat the Heat in 3D Chip Stacks with Embedded Cooling
by: Pritish R. Parida, Mark Schultz & Timothy Chainer J. Watson Research Center, Yorktown Heights NY, USA INTRODUCTION In the Moore’s Law race to keep improving computer performance, the IT industry has turned upward, stacking chips like nano-sized 3D skyscrapers. But those stacks, like the law they’re challenging, have their limits, due to overheating. A solution … [Read more...]
New Synthetic Dielectric Coolants Deviate From Traditional Petroleum-based Dielectric Oils
Image Caption: A capacitor failure on a GPU board was caused from oil absorption through the capacitor’s rubber seats while emerged in white oil. As higher clock frequencies and smaller transistor dimensions continue to increase the power density of high-performance computing technologies, such as CPUs, GPUs, FPGAs, Laser Diodes, and Optical electronics, advances in thermal … [Read more...]
Thermal Management Considerations in High Power Coaxial Attenuators and Terminations
The testing and troubleshooting of high power and high frequency systems such as distributed antenna systems (DAS), base stations, and various radar applications require buffering to prevent a power overload to the testing equipment and sensitive subsystem internal circuitry. With powers as high as 60 dBm (1000 Watts), radio frequency (RF) terminations and attenuators are … [Read more...]
What a Thermoelectric Cooler is REALLY Good For…
Fairy tales… perpetual motion machines… Not all fairy tales are perpetual motion machines, but all perpetual motion machines are certainly fairy tales. Before I get into the specifics of thermoelectric coolers, however, it seems appropriate to set the stage for this particular category of fairy tales. There are two classical types of perpetual motion “machines,” called (not … [Read more...]
