Different forms of carbon, such as processed natural graphite, pyrolytic graphite, diamond-like carbon, and synthetic diamond, offer lots of possibilities for maximizing conductive heat transfer.Synthetic diamond has already found its place as a common solution for heat spreaders inside semiconductor laser components, where temperature stabilization is of utmost importance for … [Read more...]
Advanced Techniques for IC Surface Temperature Measurement
Introduction: The Need for IC Surface Measurement Techniques Current trends in microelectronic design generate challenges in both the design and test of integrated circuits (ICs). One area that has been gaining increased relevance with regard to the microelectronic evolution is thermal management/analysis, which proves essential in the domain of IC design to prevent reliability … [Read more...]
The thermal conductivity of rubbers/elastomers
In the May 2001 issue, this column discussed the thermal conductivity of unfilled plastics. The interested reader may have noticed that the category of rubbers/elastomers was missing. This was not without reason. The user of these elastic materials should be aware that the final thermal resistance (which is, of course, from an engineering point of view, the more important … [Read more...]
Temperature and reliability in electronics systems – the missing link
To introduce the reliability requirements we face for the future, we focus on telecommunication as an example. Personal telecommunication is becoming increasingly integrated into our daily lives. However, we cannot take full advantage of the technology unless the telecommunication system is as dependable as a car. Just as turning the ignition key should produce the right engine … [Read more...]
Noise emission of telecommunication devices
Modern environmental requirements demand low noise levels for telecommunication cabinet products, especially when located in offices or urban areas. The spaces available are limited, and the power and electronics packaging density are increasing. Fans are commonly used to enhance the cooling of electronics by improving heat transfer due to higher air velocities. In this paper, … [Read more...]
