Abstract:
1. A method of fabricating a flexible circuit interposer, the method comprising the steps of: (a) providing a substantially flexible substrate having a top surface and a bottom surface; (b) defining at least one conductive trace; (c) forming a first set of pads configured in a first pad pattern on the bottom surface such that the conductive trace is electrically continuous with at least one pad in the first set of pads; (d) forming a second set of pads configured in a second pad pattern on the top surface, wherein the second pad pattern substantially corresponds to the first pad pattern; (e) forming a third set of pads configured in a third pad pattern on the top surface, wherein the third pad pattern substantially corresponds to the first pad pattern and wherein at least one pad in the third set of pads is electrically continuous with the conductive trace; (f) forming a plurality of plated through-holes such that each of the pads in the second set of pads is electrically continuous with a corresponding pad in the first set of pads; and (g) forming a bending region between the first set of pads and the third set of pads.
