This article presents an overview of a number of dynamic measurement methods as part of the European PROFIT project. Due to lack of space, details cannot be given, but the interested reader is invited to consult the references at the end of the article. Because the majority of a product's cost and performance are committed in the early phases of a design cycle, it is envisioned … [Read more...]
Dynamic Temperature Measurements: Tools Providing a Look into Package and Mount Structures
Today it is commonly accepted that dynamic thermal measurements, which have been used for more than 20 years [1], [2], [3], [4], are superior to steady-state ones. The temperature vs. time function - often called the thermal step-response function, heating curve, or thermal impedance curve - is characteristic of the chip-to-ambient structure, including even different cooling … [Read more...]
Estimating Temperatures in a Water-to-Air Hybrid Cooling System
As most readers are no doubt aware, the trend towards ever increasing processor module power is making it more and more difficult to cool directly with air. Many thermal engineers are convinced that water cooling may be the answer. This does not necessarily mean that cooling water must be supplied by the customer. Instead, in some instances it may be possible to use a … [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...]
Diamonds are a Thermal Designer's Best Friends
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...]
