7th International Workshop on

THERMal INvestigations of ICs and Systems

plus a special

Monday 24 September

Two Professional Development Courses/Tutorials (A and B) are being offered on Monday 24 September, from 9.30 a.m. to 5 p.m. They will run in parallel. Registrations will be guarantied on a first come first serve basis, upon maximum capacity is reached.

 A.  "Thermal Design Basics and Calculation of Air Cooling Limits"
    K. Azar, Advanced Thermal Solutions, Inc., Norwood, USA

From the inception of electronics, cooling by air has been the most desired and broadly implemented method in the industry. As materials, function, configuration and power dissipation of electronic systems have gone through, and will continue to experience broad changes, the question of effectiveness/practicality of air-cooling continues to surface. This is further amplified by data from different industry sectors claiming to have reached the limits of air-cooling. Hence, uttering heat flux data that beyond which higher mode of cooling is necessary! Such product-specific data has caused a concern in the industry as to whether air-cooling is a limiting option thus, higher modes of cooling are required. In this course a methodical procedure is presented for the designers to quickly calculate system performance with a given cooling option and determine the most suitable technique for the system at hand. The course is presented in two parts, the first part is designed to provide the basic calculation methodologies, and the second part address the issue of air-cooling as an option. The first part of the course will deal with basic calculations for thermal design. The second part will deal with the limits of air cooling.

Dr. Azar has been an adjunct professor at a number of universities, and lecturers worldwide in analytical and experimental methods in electronics cooling. He holds more than 26 national and international patents, has published more than 58 articles, 3 book chapters and a book entitled, "Thermal Measurements in Electronics Cooling". In addition, he serves as the Editor-in-Chief of the Electronics Cooling Magazine, and was awarded IEEE SEMITHERM Significant Contributor Award in the thermal management of electronics systems.

 B.  "Resource Management in Thermal Design of compact Electronic Equipment"
    W. Nakayama, ThermTech International, Kanagawa, Japan

Shrinking system dimensions and higher packaging density are the norm in the evolution of electronic equipment. From portable computers to massively parallel processors, the internal space of the system box becomes a precious commodity to be shared by the electronic components and the cooling media. The space availed for cooling media, the power input to the electronic devices, and the allowable temperature potential are mutually affecting design parameters, and they can be regarded as tradable resources in an effort to maximize the system performance and reliability. While such concept helps to capture the technical aspects of product design from a strategic viewpoint, the management of time, human, and capital resources is also needed to streamline the design jobs. A particularly important step in the job stream is quick assessment of the impacts of new cooling devices and techniques on the product design on hand. The following topics will be covered: evolution of hardware morphologies, resource allocation in the system design, effectiveness of various cooling methods in tight space, possible impacts of micro-fabrication based cooling technologies, development of an infrastructure to support product innovation.
