Patent ID: 7271016

Claim:
A method of testing a semiconductor device, the method comprising the steps of: (a) providing a printed circuit board having a pad region configured to accept the semiconductor device; (b) providing a flexible circuit interposer, the flexible circuit interposer comprising: (i) a substantially flexible substrate having a top surface and a bottom surface; (ii) a first set of pads configured in a first pad pattern on the bottom surface of the flexible substrate; (iii) a second set of pads configured in a second pad pattern on the top surface of the flexible substrate, wherein the second pad pattern is substantially the same as the first pad pattern, and wherein each of the pads in the second set of pads is electrically continuous with a corresponding pad in the first set of pads; (iv) a third set of pads configured in a third pad pattern on the top surface of the flexible substrate, wherein the third pad pattern is substantially the same as the first pad pattern; (v) at least one conductive trace connecting a pad in the first set of pads with a spatially corresponding pad in the third set of pads; and (vi) a bending region between the first set of pads and the second set of pads; and (c) attaching the semiconductor device to the flexible circuit interposer.
