BY: Lauren Boston, Andrew Yu, Timothy Chainer, Edward Yarmchuk, and Michael Gayness To improve cooling of electronic components, a heat spreader is typically attached to the component to spread the heat laterally and facilitate the heat removal by a heat sink. To ensure good thermal conduction between the heat spreader and heatsink, a thermal interface material is applied … [Read more...]
Researchers Create Cheap Thermoelectric Materials
A team led by Dr Ole Martin Løvvik of Oslo University’s Centre for Materials Science and Nanotechnology in Norway has found a way of making cheap thermoelectric materials that could harvest waste heat from a range of scenarios. However, attempts to bring the technology into the mainstream, in order to harvest waste heat from industrial and everyday scenarios, have been limited … [Read more...]
Thermal Management PCBs Solve Thermal Problems for LED Industry
SinkPAD Corporation’s new SinkPADTM aluminum PCB technology are a complete and effective solution to the challenges faced by the solid state lighting industry, specifically those with aluminum LED PCB applications. SinkPADTM conducts heat out of the LED system (LED conduction cooling) by enabling a direct thermal path between the LED and surrounding atmosphere. The LED thermal … [Read more...]
Talk Tackles Challenges of LED Test Standards
Defining thermal resistance for LEDs is important as some LED vendors neglect the effect of radiant flux in their calculations, which results in better data than is actually achieved in the field, noted Mentor Graphics’ András Poppe, PhD, in a recent presentation at MEPTEC’s The Heat is On event. Still another example where calculations need to be carefully weighed is … [Read more...]
Lowest Resistance, Zero Pump-Out Thermal Pad
AOS Thermal Compound’s Micro-Faze® 3 A-4 is a non-silicone thermal pad that exhibits extremely low thermal resistance. It was designed to replace phase change materials and even high performance thermal grease. The pad is composed of 1 mil films of high thermal conductivity, tacky, but dry-to-the-touch thermal grease on either side of a 2 mil aluminum foil substrate. The … [Read more...]
