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...]
Top 10 FloTHERM V10 Features – #2: Advanced Find
Electronic products, and products that contain electronics, are typified by being constructed of 100s if not 1000s of individual parts. A CPU alone is the most complex manufactured product on earth as demonstrated in this excellent picture story on Tom’s Hardware. From the IC through package, PCB and chassis, items are glued, cured, soldered, screwed and assembled into … [Read more...]
Top 10 FloTHERM V10 Features – #1: New GUI
FloTHERM V10 is a major release that marks 25 years as the leading electronics thermal simulation tool. This series will introduce the top 10 features that we’ve delivered, hopefully giving some insights not just on the features themselves, but also on the background as to how and why we’ve developed them. To start with let’s look at the most obvious change, a … [Read more...]
