Researchers at Cornell University have developed a new method of precisely measuring the subtle movement of heat in nanostructures. Heat flows at the nanoscale differently than at larger scales, the researchers say, and understanding how certain surfaces affect the transport of heat at the phonon level could have implications in everything from thermoelectric materials to … [Read more...]
TTI Analyzers Offer Low-Cost Solution for Non-Invasive Thermal Design Verification
Microsanj, a supplier of high-resolution thermoreflectance thermal imaging systems, tools and consulting services, has announced the availability of its NT100/NT110 thermoreflectance thermal image analyzers starting at $45,000.

Ultra-Thin Titanium Based Thermal Solution for Electronic Applications
Payam Bozorgi and George Fleischman PiMEMS, Inc. Introduction As electronic system technology advances with continual increases in requirements leading to greater demand for higher power consumption, there have been growing challenges related to the design of thermal engineering and heat rejection technologies. The need for performance inevitably leads to operation of most … [Read more...]
Potential Pitfalls of Hybrid Electrical-Thermal Measurements for Thermal Characterization
Anurag Gupta, David H. Altman, Daniel P. Resler Raytheon Integrated Defense Systems Introduction Electrical resistors are often used to simulate heat-dissipating electronic devices in thermal characterization of semiconductor devices. This article describes a study in which test measurements and analysis were conducted in steady-state conditions to characterize the thermal … [Read more...]
Towards Reproducible ASTM D5470 Measurements at Lower Cost
Baratunde A. Cola Georgia Institute of Technology INTRODUCTION ASTM D5470 (updated to ASTM D5470-12 in 2012) [1] remains an industry standard for characterizing thermal interface materials (TIMs) despite some drawbacks. Ultimately, a TIM must be tested in its application to conclude its merits. Standardized testing is useful, however, for comparing TIMs in research and … [Read more...]
