INTRODUCTION Militaries continue to expand their use of electronics in harsh environments while preserving an absolute minimal risk of failure. In this regard, effort spent early in the design process on concept development, parametric and trade-off studies, and simulation-driven design can yield amplified benefits in terms of product performance and reliability, reduced … [Read more...]
New Micro-Sized DC Blower Virtually Silent
JARO's new micro-sized "Whisper" (TM) Blower measures in at an impressively tiny 20 X 20 X 6 mm (6000 RPM ± 20%), and offers a virtually-soundless operation. Thanks to a unique Aerospace-Fluid Bearing system, this new micro-sized DC blower provides exceptionally high static pressure, while offering a very low operating volume (16 dB). The new blower offers a super-low … [Read more...]
Cooling Circuits with Nanochimneys in Carbon Nanotubes
The extraordinary properties of Graphene are well known, and in the context of electronics thermal management and reliability, it is about 200 times stronger than the strongest steel and conducts heat and electricity very efficiently. Both graphene and carbon nanotubes consist of six-atom rings, which create the well-known hexagonal Honeycomb structure, and both excel at the … [Read more...]
Thermal Facts & Fairy Tales: 7 years of college down the drain…
...might as well join the Peace Corps… - John "Bluto" Blutarsky1 I would hazard a guess that the majority of people bothering to read an article on electronics cooling likely work in the electronics industry. Moreover, it is probably a pretty good bet that a lot of them have actually taken a class on heat transfer at some point. Since most of us eventually graduated, it … [Read more...]
Rogers Corporation Launches Cost-Effective Laminates for Automotive Radar Sensor Applications
Rogers Corporation announced the latest addition to its RO4000® Series thermoset circuit materials: RO4830™ high-frequency laminates. RO4830 laminates offer 76-to-81-GHz auto radar sensor designers a lower-cost-but-performance-competitive option. Rogers RO4830 laminates are processed by means of standard epoxy/glass (FR-4) circuit fabrication methods, for lower overall … [Read more...]
