Via and Trace Currents and Temperatures

Speaker

Doug Brooks and Dr. Johannes Adam

Duration
 32min 56sec

Stop thinking about current density!

In this 30-minute video, Doug Brooks and Dr. Johannes Adam explain the material parameters and properties that determine the temperature of a trace, how these are calculated, and show results of some simulations of vias of varying widths and amps.

Brooks and Adam are coauthors of several publications on trace and via temperatures, including PCB Design Guide to Via and Trace Currents and Temperatures and Predicting Fusing Time of Overloaded PCB Traces Can We Predict It At All?
