Abstract
A flexible circuit (FC) comprises a primary dielectric layer having a plurality of substantially parallel conductive circuit traces disposed therein and a secondary dielectric layer extending from or attached to the primary dielectric layer, wherein the secondary dielectric layer does not have any conductive circuit traces disposed therein, and wherein at least one of the primary and secondary dielectric layers defines an alignment feature for wrapping and securing the FC about a central structure. A method of wrapping and securing the FC about a central stricture comprises wrapping the FC about the central structure while aligning each alignment feature with a respective complimentary alignment feature such that the FC fully encompasses the central structure and is secured thereabout.
