Abstract
A single circuit board assembly for forming a vehicle-motor interface includes a first side of a board with logic modules located thereon. The single circuit board assembly also includes a second side of the board with power modules located thereon. The board includes a first plurality of layers and a second plurality of layers, and a dielectric layer disposed between adjacent layers of the first plurality of layers and/or the second plurality of layers, the dielectric layer comprising polytronics material.
Claims13
A single circuit board assembly for forming a vehicle-motor interface, the single circuit board assembly comprising:
- a first side of a board with logic modules located thereon;
- a second side of the board with power modules located thereon;
- wherein the board comprises a first plurality of layers and a second plurality of layers, wherein the first plurality of layer and the second plurality of layers are formed of copper, the board further comprising a dielectric layer disposed between adjacent layers of the first plurality of layers and/or the second plurality of layers, wherein the dielectric layer is one of a plurality of dielectric layers, each of the plurality of dielectric layers disposed between a respective pair of adjacent layers of the first plurality of layers and the second plurality of layers, wherein the first plurality of layers are located adjacent the first side of the board and the second plurality of layers are located adjacent the second side of the board, wherein the first plurality of layers has a first total thickness and the second plurality of layers has a second total thickness, wherein the first total thickness is different than the second total thickness.
A motor assembly for a vehicle steering system comprising:
- a motor housing;
- a heat sink assembly operatively connected to an end of the motor housing, wherein the heat sink assembly defines a pocket on a single side of the heat sink assembly;
- and
- a circuit board assembly in operative communication with the motor housing and disposed at least partially within the pocket of the heat sink assembly, the circuit board assembly comprising:
- a first side of a board with logic modules located thereon;
- a second side of the board with power modules located thereon;
- wherein the board comprises a first plurality of layers and a second plurality of layers, wherein each of the layers are formed of copper, the board further comprising a dielectric layer disposed between adjacent layers of the first plurality of layers and/or the second plurality of layers, wherein the first plurality of layers has a first total thickness and the second plurality of layers has a second total thickness, wherein the first total thickness is different than the second total thickness.
