electronics cooling in the automotive environment
Introduction By 2008 the electronics content of a typical consumer vehicle had grown to 20-25% of the total vehicle cost [1]. This content provides a wide range of functions and features for today’s driver. Some features such as the radio/audio system and instrument cluster are quite familiar and visible to the driver and have been mainstays in the automobile for many years. … [Read more...]
Health Assessment and Prognostics of Electronic Products: An Alternative to Traditional Reliability Prediction Methods
Introduction Traditional handbook-based reliability prediction methods for electronic products include Mil-Hdbk-217, Telcordia SR-332 (formerly Bellcore), PRISM, FIDES, CNET/RDF (European), and the Chinese GJB-299. These methods rely on analysis of failure data collected from the field and assume that the components of a system have inherent constant failure rates that are … [Read more...]
LED Thermal Standardization: A Hot Topic
Introduction The main topic of the article is how to cope with the increasing need for standardization of thermal characterization of LEDs (Light Emitting Diodes) and LED-based products (see Fig.1 showing a typical LED package). The LED-business is growing much faster than analysts predicted five years ago. Unfortunately, the progress in thermal characterization has not kept … [Read more...]
