Dirk Schweitzer Infineon Technologies AG Introduction The junction-to-case thermal resistance Rth-JC is an important thermal characteristic especially for power semiconductor devices. Its value is often one of the main criteria for the decision whether a device can be used in a specific application and a low Rth-JC is a competitive advantage for the semiconductor manufacturer. … [Read more...]
evaluation of cooling solutions for outdoor electronics
INTRODUCTION Outdoor enclosures for housing electronic circuit boards are widely used in a variety of technologies, including telecommunications, industrial and military applications. These enclosures protect the equipment against a wide variety of environmental hazards, such as sun, moisture, dust and debris. As electronic components have become more powerful and complex, … [Read more...]
technical brief: thermal bottlenecks and shortcut opportunities; innovations in electronics thermal design simulation
Introduction Cooling an electronics system involves transferring heat from various heat sources to the outside ambient. Thermal simulation software provides practitioners with predictions of the temperature and heat flux distributions in and around the system, making it easy to assess the impact of design changes. While the raw simulation results enable us to measure and … [Read more...]

what's happening
Melting-While-Cooling Silicon Could Improve Solar Cells Researchers at the Massachusetts Institute of Technology (MIT) have recently discovered that by dissolving certain metals into silicon, they can add that silicon compound to the relatively short list of exotic substances that exhibit retrograde melting. Their accomplishment could ultimately result in less expensive solar … [Read more...]
