Abstract The past two decades have seen many approaches to solder fatigue and solder joint life published. This subject has proved difficult as various failure mechanisms are proposed and examined. While these theoretical bases are discussed, it often leaves the end developer in a difficult situation as to how to apply an accurate simulation approach to fatigue failure for a … [Read more...]
Radiation Basics: Making Sense of Emissivity & Absorptivity
Introduction This is the second installment in a series of articles that aims to explore a range of practical topics on radiation that are relevant to those of us focused on electronics cooling and thermal design. The last article [3] provided guidance regarding when radiation matters, with examples being natural convection environments, space applications, solar collectors, … [Read more...]

Mitigating Flow Maldistribution in Data Center Two-Phase Cooling Systems with Flow Restrictors
By Serdar Ozguc, Qingyang Wang, Akshith Narayanan, Richard W. Bonner III The Need for Two-Phase Cooling in Data Centers Power usage in data centers account for 1.8% of the overall electricity expenditure in the United States [1] and the cooling infrastructures make up 50% of the total energy consumption of the data centers [2]. Power consumption translates to high … [Read more...]
