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...]
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...]
