Researchers at the Niels Bohr Institute have discovered a new method for laser cooling semiconductor membranes. Semiconductors are vital components in solar cells, LEDs and many other electronics, and the efficient cooling of components is important for future quantum computers and ultrasensitive sensors. Using lasers, researchers cooled membrane fluctuations to minus 269 … [Read more...]
Graphene as a Thermal Conductor
A joint U.S.-Chinese research team has demonstrated that the thermal properties of isotopically engineered graphene are superior to those of natural graphene. The demonstration could potentially strengthen the possibility of using graphene to manage heat dissipation. “The important finding is the possibility of a strong enhancement of thermal conduction properties of … [Read more...]
Bottlenecks and Interface Materials; Part 2 – When TIMs Go Bad
‘Bits stuck onto other bits’, a succinct definition of an electronic product, if not a product that contains electronics. Soldering is the method of choice for getting the components to attach to the pcb, the layered board that contains the metallic traces connecting component pins to other component pins. Rivets, welds, screws or bolts for the chassis, some form of … [Read more...]
Has Your Brand Image Been Hijacked?
Electronics Cooling Business Bulletin Volume 6 | January 2012 In a recent article entitled “Who is Managing Your Brand Image?” my colleague, Graham Kilshaw, explained how customer behavior has effected a significant shift in marketing, from direct response advertising to brand advertising. As customers gather on social sites where they share opinions and, in turn, are … [Read more...]
Bridging the Simulation Supply Chain; NXP Semiconductors, a Case in Point
By far and away the most common enquiry by someone using FloTHERM, especially at the start of their adoption, is “How do I model my components?”. This is hardly surprising as the mainstay of electronics thermal management is the control of operating component temperatures (junction and/or case). A virtual prototyping design by simulation approach requires models of components … [Read more...]
