Technical Data Summary
ElectronicsCooling magazine has been providing a technical data column since 1997 with the intent of providing you, the readers, with pertinent material properties for use in thermal analyses. We have largely covered the most common materials and their associated thermal properties used in electronics packaging and as a result, this column will evolve into additional topics. … [Read more...]
Mini- and Microchannels in Thermal Interfaces: Spatial, Temporal, Material, and Practical Significance
Introduction The role of thermal interface materials (TIM) to augment heat flow in electronics has been well-documented [1-4]: Higher thermal conductivity (k) and thinner bondlines proportionally reduce the interface thermal resistance (RTH). Today's high-performance TIMs contain micro- and nanometer-sized particles to increase the effective TIM thermal conductivity (keff,TIM) … [Read more...]
Advanced Metal Diamond Composites – Love and Heat Relationship
Introduction Thermal management is a critical issue in high-power laser diode and LED packages, and microprocessor units [1, 2]. Reliability and long life time of electronic packages call not only for materials with high thermal conductivity but also a coefficient of thermal expansion (CTE) matching to that of semiconductors. The thermal expansion of the heat sink material in … [Read more...]
Emissivity in Practical Numerical Modeling
In the August 2003 issue, the Technical Data column was devoted to emissivity in practical temperature measurements. But what about the emissivity value that should be entered in your numerical model? Can we use the measured values as discussed in the column mentioned? Let me summarize the main points of it: Emissivity is not only a material property but also a surface … [Read more...]
