Abstract

A two-dimensional, steady-state thermal conduction analysis is made on a finite, plane homogeneous medium (a printed circuit board, or PCB) to examine the trace behavior. The trace is modeled as a zero-thickness, strip heat source with specified uniform temperature, and its position in the medium is varied. A two-dimensional thermal analysis is also performed on a multilayered cell model with finite heat source to establish an accurate, effective thermal conductivity for a typical PCB
