Thermal characterisation forms an integral part of the specification of all electronic components, and standard test methods have been developed to evaluate this feature. However, the applicability of these results is being questioned because a range of values can be obtained, depending on the interpretation of the test method and variation of test conditions. The experimental approach used in the study highlights the effects of some factors such as board copper content and orientation, lead contact with the board, power level, and local air temperature on the thermal characterisation of a board mounted 160 lead Plastic Quad Flat Pack (PQFP) in a natural convection environment. This information should also prove useful to electronic system designers.
