At the Speed of Heat

Posted by Robin Bornoff

Robin Bornoff Many analogies exist relating heat flow to fluid flow. Oops, there’s one. A good electronics thermal design is one that gets the heat out from the heat sources quickly and the cold in to quench them quickly. Before I scoot off to sunny (though heavy rain is forecast) Devon for a family holiday I thought I’d leave you with this… Thermal power dissipation is measured in Watts (W) A Watt is a Joule/second … Read More

Temperature, Power Dissipation

24 Jul, 2009

Robin Bornoff Thought I’d follow the previous post on this subject up with a slightly more detailed description of exactly how to set-up a model with a fixed temp die and observe the resulting simulated power dissipation. “Hey Robin, this should really be done as a AppNote on SupportNet”. Can’t argue with that but posting it here as well will give everyone a glimpse of the actual operation of FloTHERM and FloTHERM.PCB. So, … Read More

Power Dissipation, Temperature

21 Jul, 2009

Robin Bornoff Electronic thermal simulations are most commonly formed by specifying a power dissipation within a package and using numerical solution techniques to derive what the resulting temperatures are within and around the package, PCB etc. If the package temperature is too high you’ve got issues that you’ll need to resolve via various thermal management approaches. You can turn the model definition on its … Read More
