    Abstract: A substrate, a chip, a circuit package and a process of fabricating a substrate are presented. The substrate is provided between an integrated circuit and a printed circuit board, and comprises a core insulating and a buildup insulating layer. The first plated through hole is operable to provide ground through from the printed circuit board to the integrated circuit. The second plated through hole is operable to provide electrical communication carrying signals or power between the integrated circuit and the printed circuit board through the buildup insulating layers. The first plated through hole is formed in tubular shape defined an outer wall and an inner wall, and the second plated through hole is formed in the inner wall and is insulated with the first plated through hole.

    Abstract: A drive unit for driving a motor has a component assembly including a main circuit board having a component side and a solder side, one or more main circuit conductors formed in at least one layer of the main circuit board, a power component module including one or more power components, the power component module having electrical connection terminals for connecting the power component(s) to the one or more main circuit conductors of the main circuit board and a cooling plate coupled to the power component(s) in a manner enabling transfer of heat from the power component(s) to the cooling plate. The power component module is mounted to the component side of the main circuit board. The component assembly further includes a heat sink mounted on the cooling plate and a fan mounted on the heat sink.
