Joule heating temperature prediction for inductor

The aim of this work is to define a joule heating prediction tool under DC stress for thick copper/Low-k inductors on glass substrate technology. The thermal resistance experimental results have been approximated by an empirical model and, combined with thermal coefficient of resistance formalism; allow us to define an analytical temperature joule heating formula. This analytical joule heating formula can be widely used to define the maximum operating conditions and able to be implemented in design rules manuals.
