Silicon Sponge Ideal for Lithium-Ion Battery Pack Assemblies
Saint-Gobain Performance Plastics Foams announces R10404, a thermally conductive, silicone sponge ideal for lithium-Ion battery pack assemblies. Key properties include thermal conductivity, electrical isolation and compression set resistance, which makes the material well-suited for controlling operating temperature and mitigating electrical and vibration hazards. Read the … [Read more...]
The Better Box Model
Introduction For the consumer, natural convection cooling or fan-less cooling is the method of choice. It is silent, it is reliable, it is simple, and it is environmentally sound because no additional energy is used to remove the excess heat. For the thermal engineer, fan-less cooling is more problematic. On the plus side, no fan is needed, so there is an attractive cost … [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...]
