Editor’s note: This question was asked in response to Electronics Cooling’s recent webinar by Carl Zwebin. To view the webinar, click here. Question: Are these graphite based materials compressible? Answer: In general, they are not compressible. However, exfoliated natural graphite is compressed during the manufacturing process used to make thermal interface materials and … [Read more...]
Waterproof Tablet Computer Features Cooling Fan
Electronics manufacturer Fujitsu has released a unique new tablet computer capable of operating underwater while using a cooling fan to pump heat away from sensitive internal circuitry. The Arrows Tab QH77/M is 2-in-1 computer that can be used both as a clamshell notebook computer and as a tablet computer when the display unit is detached. The casing houses an Intel Core … [Read more...]
Nanodiamond Filler Ups Conductivity of Thermally-Conductive Polymers
Carbodeon, a supplier of superhard materials such as nano-diamonds and graphitic carbon nitride, has released a new thermally-conductive nanodiamond filler it claims increases the conductivity of thermally-conductive polymers by 25 percent. According to the company, the increase in thermal conductivity is achieved without affecting the electrical insulation or other mechanical … [Read more...]
Thermal Connectors Improve PCB Assembly Heat Dissipation
TEM Products Inc., a manufacturer of mechanical components for electro-mechanical assembly, has released its new patent-pending PowerPeg thermal connectors. Designed for attachment to an external dissipater, the new PowerPeg thermal connectors offer significantly improved thermal conductivity compared to traditional PCB heat spreading methods by allowing heat to dissipate more … [Read more...]
Thermal Venting with Thermal Vias
Thermal vias are merely one tool, albeit sometimes an important tool, in the thermal engineer's arsenal of techniques for getting heat away from potentially overheating electronics components. The problem is, vias don't actually "cool" a hot device in and of themselves. As their name implies ("vias"), what they really are is nothing more than a short pathway for unwanted heat … [Read more...]
