So, you want to predict component temperatures do you? Part VI

Posted Dec 17, 2009, by Robin Bornoff

On the sliding scale of thermal component model representation king of all is a ‘detailed’ model. A 3D definition of all of the internal construction geometry and material properties does away with any of the accuracy inconsistency issues associated with the derived CTM (thermal resistor network type) approach. Despite the fact that all models are wrong a detailed model representation of a package … Read More

So, you want to predict component temperatures do you? Part V

Posted Dec 7, 2009, by Robin Bornoff

Like a river this blog series is slowing down due to its increased width and depth, that and a lot of travel on my part. So, let’s get it back on track! The previous blog focussed on the relatively well known 2 resistor compact thermal model (CTM) method, its strengths (simple to measure and describe) and its deficiencies (unconfirmed and inconsistent accuracy for different package styles and operating … Read More

“All models are wrong, but some are useful” Part III

Posted Jun 5, 2009, by Robin Bornoff

The next two parts in this series focus on the thermal model representations of electronic objects. The first being packages, or should that be components, or chips? From a mechanical analysis perspective they're the things that are plonked onto a PCB that get hot. These things do clever electrical stuff, or should that be electronic stuff? If you haven't already guessed I'm a mechanical engineer with … Read More
