Low-emissivity (Low-E) films are not new –they represent a mature technology in which a metal-oxide coated surface emits low levels of radiant thermal energy. Low-E films are widely used on window glasses in energy-efficient buildings. Low-E materials include metals like Aluminum foil which has a thermal emissivity /absorptance of 0.03 which means that it reflects 97 percent of … [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...]
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...]

Cooling the DARPA Space Surveillance Telescope (SST)
by MP Divakar, PhD, Stack Design Automation Technical Editor, Electronics Cooling With many nations joining the race of sending satellites out to space, the number of orbiting space debris is increasing year after year. This NASA portal estimates the number of space junk as over 500,000 orbiting earth at speeds of 17,500mph or higher. Most of the half-million plus objects … [Read more...]
