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...]
When Moore Is Less: Exploring the 3rd Dimension in IC Packaging
Introduction As consumers of electronics we have become spoiled. We not only expect our electronic devices to get smaller, faster, more functional, cheaper, more interconnected, and more reliable, we actually demand it. It would not be a pretty picture either for the consumer or the electronics industry if suddenly the design of our electronic gadgets became static. At this … [Read more...]
A Cryocooler In Your Laptop Computer? Maybe…
Introduction A review of the technical and market impediments overcome in the development and eventual acceptance of cryocoolers for space-borne applications may shine light on the prospects for the use of such mechanical refrigeration systems in more widespread commercial uses. This premise is explored by first reviewing space cooler development history, then considering some … [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...]
