Abstract: A method for making a printed circuit board (PCB) with a tridimensional (3D) dielectric substrate having opposite sides and made of fiber-reinforced polymer. Each side comprises channels and pockets formed by molding or machining a dielectric laminate, and the channels and pockets define a layout for conductive traces and pads of the PCB. The channels and pockets in a same side of the 3D dielectric substrate have a uniform depth. Side walls of the channels and pockets have a draft angle in a range of at least about 5 degrees to at least about 15 degrees.

Abstract: A device has a housing and a rotor with an axis and a rotor disk with a magnet. A cooling plate is coupled to the housing. The cooling plate includes a channel connected to an inlet and an outlet to convey a liquid coolant. A stator is coaxial with the rotor and includes a printed circuit board with conductive layers laminated together with layers of an insulating material. Each conductive layer has coils that can carry electrical current when connected to an external voltage source. The stator is mechanically coupled to the housing, so the stator reacts to torque produced by the device. A ferromagnetic yoke is mechanically and thermally coupled to the stator and to the cooling plate to provide a path for magnetic flux produced by the magnet and a path to conduct heat generated by the stator from the stator to the cooling plate.
