Abstract

The thermal characteristics of a wire-bond COB package with a calibrated thermal chip was investigated by wind tunnel experiments and finite element analysis. Thermal measurements were carried out in a wind tunnel used to simulate steady state natural and forced convection heat transfer conditions. Finite element analysis of the steady state heat transfer condition was simulated using a two-dimensional model of the wire-bond COB package. The finite element model was also employed in a thermal stress analysis of the wire-bond COB package subjected to accelerated thermal cycling loading
