Abstract
A substrate assembly for use with a high power switching module includes at least one power block having a base plate for providing mechanical rigidity for the power block. The power block also includes at least one silicon die mounted onto the base plate and configured to form at least one high power switching transistor having leads extending away therefrom. The power blocks are then supportably mounted into corresponding apertures in a rigid frame which mounts the power switching module onto a heat dissipating surface and tested independently before mounting into the frame at full load current and power, which cannot be performed at the bare die level.
