1. A method of fabricating components for a three-dimensional circuit structure, the method comprising:
providing a printed circuit board (PCB) having a top surface, an opposing bottom surface, a first height, and an end section; forming a first angled channel in the top surface at the end section of the PCB, wherein the first angled channel extends to an edge of the end section and divides the end section into a first end portion and a second end portion; removing PCB material from the top surface at the first end portion to form a first support member having an upper surface at a preselected distance below the top surface; forming a second angled channel in the bottom surface at the end section of the first PCB, wherein the second angled channel extends to the edge of the end section and is adjacent to the first support member; and removing PCB material from the bottom surface at the second end portion to form a second support member having an upper surface that is contiguous with the top surface of the PCB, wherein a ramp portion extends between the first support member and the second support member, the ramp portion having a first size and shape. |
