Abstract:
This disclosure relates generally to substrates having three dimensional (3D) inductors and methods of manufacturing the same. In one embodiment, the 3D inductor is a solenoid inductor where the exterior edge contour of the winding ends is substantially the same and substantially aligned with the exterior edge contour of the exterior edge contour of conductive vias that connect the windings. In this manner, there is no overhang between the windings and the conductive vias. In another embodiment of the 3D inductor, via columns connect connector plates. The via column attachment surfaces of each of the conductive vias in each of the columns is the same and substantially aligned. In this manner, carrier pads are not needed and there is no overhand between the conductive vias.
