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...]
