Claim 6:
7. The method of claim 1, wherein:
the one or more first conductive coiled traces comprise a first conductive coiled trace on a first side of the first flexible PCB and a second conductive coiled trace on a second side of the first flexible PCB, wherein the first flexible PCB comprises an insulating layer separating the first side from the second side;
the first flexible PCB further comprises a via through the insulating layer electrically connecting the first conductive coiled trace with the second conductive coiled trace;
the one or more second conductive coiled traces comprise a third conductive coiled trace on a first side of the second flexible PCB and a fourth conductive coiled trace on a second side of the second flexible PCB, wherein the second flexible PCB comprises an insulating layer separating the first side from the second side; and
the second flexible PCB further comprises a via through the insulating layer electrically connecting the third conductive coiled trace with the fourth conductive coiled trace.
