Patent ID: 7649254

Claim:
A structure for providing rigidity to an area of less than all of the area of a flexible substrate, the structure comprising: a first adhesive over a certain area of the flexible substrate, the first adhesive having an opening over an electrical conducting portion of the flexible substrate and adhering to a portion of the structure that is adjacent to a lower surface of the first adhesive; an electrically insulating layer between the first adhesive and the flexible substrate, wherein the electrically insulating layer includes an opening approximately located under the opening of the first adhesive, the opening of the electrically insulating layer approximating the size of the opening of the first adhesive; an electrically conducting layer between the first adhesive and the electrically insulating layer, wherein the electrically conducting layer includes an opening approximately located under the opening of the first adhesive, the opening of the electrically conducting layer approximating the size of the opening of the first adhesive; a second adhesive within a cavity defined by the opening of the first adhesive, wherein the second adhesive is electrically conducting, and wherein the second adhesive is disposed over and adjacent to the electrically conducting portion of the flexible substrate; and a stiffener adhered to the structure by both the first and the second adhesive, wherein the stiffener is in contact with each of the first and second adhesives.
