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...]
Use of JEDEC Thermal Metrics in Calculating Chip Temperatures in Packages with Attached Heat Sinks
Bruce Guenin Associate Technical Editor, Electronics Cooling INTRODUCTION The previous column, "Use of JEDEC Thermal Metrics in Calculating Chip Temperatures (without Attached Heat Sinks)" dealt with the application of JEDEC thermal metrics to IC packages that do not have heat sinks attached to them [1]. The methods are applicable to prediction of the junction … [Read more...]
Cooling Fans for 1U Rack Applications
Thermal management product designer US Tech has released three new high performance fan series for use in 1U rack applications. The 36mm model produces 24.16 CFM of air volume and 67.52 mm-H2O pressure. In addition, its adherence to the 1U spec of 1.75” (44.45mm) outside to outside tall will leave enough height to design a FRU (Field Replaceable Unit) if desired. The 38mm and … [Read more...]
Thermoelectrically-Cooled Electronic Enclosure Line Expanded for More Applications
EIC Solutions, a manufacturer of thermoelectric air conditioners, electronic enclosures and transit cases, has expanded its line of pre-packaged electronic enclosures with new sizes to meet more applications. Designed to protect and cool electronics and electrical devices, the Protector series pre-packaged enclosures combine several of EIC's standard cabinet sizes with … [Read more...]
Prehistoric Cave Paint to Shield Solar Spacecraft
A European spacecraft scheduled for launch towards the sun in 2017 will be shielded from extreme temperatures by a type of paint once used in prehistoric cave art. Carrying instruments to perform high-resolution imaging of the sun, the European Space Agency’s Solar Orbiter will travel as close as 42 million kilometers, or a little more than a quarter of the distance to Earth, … [Read more...]
