Flip Chip (FC) technology offers many advantages over conventional surface mount technology, including a smaller device footprint and higher interconnection density. Low power but complex consumer items, such as mobile telecommunications devices, utilise this packaging technology and it is likely to spread to other electronics sectors where components have higher power dissipations and/or they have to operate in a hostile environment. As the scope for FC packaging broadens, a reliable means of establishing the long term performance of a particular package is necessary. Traditionally thermal cycling has been a primary reliability test for electronic assemblies including FC, however this fails to capture the behaviour of assemblies where the component thermal expansion is well matched to that of the substrate due to the isothermal heating and cooling of the assembly. In this situation power cycling offers an alternative means of determining the module performance.
