Patent ID: 7838101

Claim:
A flexible conductive ribbon material bonded to an underlying surface, the flexible conductive ribbon material comprising: an upper surface of the flexible conductive ribbon material including a first portion, a second portion, and a third portion, the third portion being defined by a plurality of indentations extending below the second portion; and a lower surface contacting the underlying surface, wherein the flexible conductive ribbon material has a first thickness between the first portion of the upper surface and the lower surface, a second thickness between the second portion of the upper surface and the lower surface, and a third thickness between the third portion of the upper surface and the lower surface, the first thickness being greater than the second thickness, and the second thickness being greater than the third thickness, wherein a first area of the flexible conductive ribbon material below the first portion is unbonded with respect to the underlying surface, a second area of the flexible conductive ribbon material approximately below the second portion is bonded to the underlying surface at a first strength, and a third area of the flexible conductive ribbon material approximately below the third portion is bonded to the underlying surface at a second strength, the second strength being greater than the first bond strength.
