Co-authored by: Feng Zhou, Shailesh N. Joshi, Ercan M. Dede Electronics Research Department, Toyota Research Institute of North America, 1555 Woodridge Ave., Ann Arbor, MI 48105, US INTRODUCTION In 2012, vehicle fuel-efficiency standards were announced that require all US cars and light trucks to reach 54.5 miles per gallon on average by model year 2025. As a result, … [Read more...]
Thermal Management and Safety Regulation of Smart Watches
ABSTRACT A smart watch is one of the most popular wearable devices now. Along with battery life and security, thermal safety is the most common concern. We show how to meet the ergonomic standards for users and predict thermal performance in typical scenarios. Thermal simulation software applied at the design stage can provide guidance on the use of heat spreading materials … [Read more...]
Reliability of Nano-sintered Silver Die Attach Materials
Coauthored by: Ross Wilcoxon, Mark Dimke, Chenggang Xie Rockwell Collins INTRODUCTION Die attach can play a significant role in the package level thermal resistance of wire bonded devices. Die with moderate heat flux can often be attached to the carrier substrate with organic, Silver Filled Die Attach (SFDA) materials that require relatively benign processing requirements … [Read more...]
Thermal Management of On-board Chargers in E-Vehicles
Electric vehicles are poised for a rapid growth phase with the combined effect of longer range, lower battery cost and faster charging rate. In particular, sales of plug-in electric vehicles (PEV) have tripled since 2013 and continue to grow at over 40% a year. It is expected that at these growth rates, 8 out of 10 new cars sold globally in 2030 will be a PEV. In some countries … [Read more...]
Does a 10°C Increase in Temperature Really Reduce the Life of Electronics by Half?
This may seem like a silly question to ask in a magazine entitled “Electronics Cooling”, but why do we really care what temperature of electronics really is, anyway? The simple answer to that question is that it is universally recognized that electronics reliability when devices are too hot for too long of a time. The difficult answers to the question are in defining exactly … [Read more...]
