JEDEC Thermal Standards: Developing a Common Understanding The Joint Electron Device Engineering Council (JEDEC) was established to provide recognized technical standards for a wide range of applications, from how to handle electronic packages and defining package outline drawings, to the methods used to characterize performance, including thermal. The JC-15 committee … [Read more...]
Summary of the IEEE ITherm 2019 Conference
Technical Brief John F. Maddox, Ph.D., P.E. The IEEE Intersociety Conference on Thermal and Thermomechanical Phenomena in Electronic Systems (ITherm) was held at the Cosmopolitan Hotel and Casino in Las Vegas, NV from May 28-31, 2019. This was the 31st Anniversary of ITherm, first held in 1988. The conference was historically held every other year until 2016 when it … [Read more...]
What…Use Lasers and LEDs for Cooling?
In a recent blog “Some New Cooling Ideas are Needed Here,” I suggested (hoped?) that someone would figure out how to leverage the thermal laws of physics to devise innovative cooling systems which go beyond widely used, conventional techniques of conduction, convection, and radiation. The reason for looking beyond these solutions is that they seem to have reached a limit as to … [Read more...]
Air Ionization Techniques for the Cooling of Electronic Devices: Analysis of the Different Effects of Design Features on Cooling Performance
Rotary fans have been used to cool electronic devices using forced convection applications to achieve the required heat transfer dissipation. In recent years, there has been an increasing trend to miniaturize the size and maximize the efficiency of the electronic devices which, in turn, increases heat generation. The use of rotary fan cooling conflicts with these new trends due … [Read more...]
Managing Cooling Fan Noise In Product Design
ABSTRACT Cooling fan noise is a system property determined as much by thermal and mechanical design and fan selection as by a fan’s acoustical design. While even the quietest fan can be used in a noisy manner, a significant fraction of unpleasant surprises can be avoided. NOMENCLATURE C Numerical constant D … [Read more...]
