ABSTRACT:
A multilayer circuit board system or laminated circuit board system for use in a motor controller includes at least two motherboards, at least one power substrate circuit board, and a capacitor circuit board. The circuit boards are mounted in an aperture or trench within each mother board. The power substrate module circuit board includes a mounting area provided in a recess, window or portion of the circuit board where the circuit board is only a single layer thick. The single circuit board layer at the mounting area provides a heat conductive yet highly electrically insulated mounting area for receiving a heat sink. The heat sink can be mounted on a side opposite the electrical device. The capacitor circuit board, power substrate circuit board, and mother circuit boards are interconnected without the use of external connectors or wires. The use of two mother boards increases the rigidity of the circuit board system.
