What have you been up to?
I have been working with Johannes Adam, who has developed software that can simulate trace temperatures on traces as a function of current. It’s called TRM (thermal risk management). Most impressively, we’ve been able to determine the temperature of a via. No one has been able to come up with this statistic in the past. We were able to show how much the via temperature changed as current changed.
