Abstract:
The investigation deals with the numerical solution of the 3D heat conduction equatioin and study variation of the effective conductivity of PCB with different component size. Cases with and without a copper layer on the component side and different PCB thicknesses were investigated. It was shown that the effective thermal conductivity of a PCB with/without a copper layer on the component side would be larger/smaller than the values given by the one-dimensional effective thermal conductivity model if the components mounted on the PCB were smaller than the PCB itself. The differencewas more pronounced for smaller components. Correlations were obtained for the effective thermal conductivity of PCBs.
