All phase change thermal interface materials are designed to minimize the thermal resistance in an interface between a heat generating component and a heat sink. How well they achieve this goal in a specific application depends on how judiciously their phase change characteristics are matched to the interface specifications. The purpose of this paper is to present the results … [Read more...]
The thermal conductivity of aluminum oxide
Aluminum Oxide (Al2O3) is an important ceramic for the electronics industry. Besides its use as a passivation layer on Silicon, the ceramic is often used as a carrier for thick and thin film passive components and for other small printed circuit boards. A relatively low cost is combined with a relatively high thermal conductivity, especially when compared to FR4 board material. … [Read more...]
Graphite fiber reinforced al and cu alloys for thermal management applications
Technological advances in the electronics industry have revolutionized the way the world communicates and conducts business. Today's electronic products, from cellular phones to sophisticated imaging satellites, demand lightweight, low-cost materials that provide more functionality in less volume. To meet these challenges, electronic systems must dump large amounts of waste … [Read more...]
The thermal conductivity of pure metals
As discussed previously in this section, the measurement of the thermal conductivity is notoriously difficult. The consequence is that, while the measurement accuracy by individual researchers is claimed to be of the order of 2%, laboratories participating in round-robin tests produce results differing from each other by 15% or more [1]. Even the measurement of pure metals is … [Read more...]
Recent Japanese thermal solutions for portable computers
Introduction Mobile computing is poised to shape the way we live our lives, allowing people to generate, retrieve, and process data anywhere and at any time. The infrastructure for mobile computing is rapidly developing, as evidenced by the recent growth of cellular phone networks and a constant stream of innovations in portable electronic equipment.
