Conductor pad for flexible circuits and flexible circuit incorporating the same
View Patent ↗A conductor pad and a flexible circuit including a conductor pad are provided. The conductor pad includes a first contact region, a second contact region, and a body portion configured to establish a conductive path between the first contact region and the second contact region. The body portion includes a perimeter edge having at least a first convex segment and a second convex with a first non-convex segment disposed between the first convex segment and the second convex segment. A method of constructing a flexible circuit to facilitate roll-to-roll manufacturing of the flexible circuit is also provided.
1. A conductor pad comprising:
a first contact region;
a second contact region; and
a body portion configured to establish a conductive path between the first contact region and the second contact region, the body portion comprising conductive material having a perimeter edge, the perimeter edge comprising:
a first convex segment;
a second convex segment;
a first non-convex segment disposed between the first convex segment and the second convex segment;
a third convex segment;
a second non-convex segment disposed between the second convex segment and the third convex segment;
a fourth convex segment; and
a third non-convex segment disposed between the third convex segment and the fourth convex segment;
wherein the second convex segment defines an outermost edge of the perimeter edge at a distance H 2 from the horizontal axis, wherein the fourth convex segment has a fourth convex segment outermost edge at a distance H 4 from the horizontal axis, and wherein the distance H 2 is greater than the distance H 4 .
2. The conductor pad of claim 1 , wherein the first non-convex segment is a concave segment.
3. The conductor pad of claim 1 , wherein the first contact region and the second contact region are intersected by a horizontal axis of the conductor pad.
4. The conductor pad of claim 1 , wherein the first contact region and the second contact region are vertically spaced from each other relative to a horizontal axis of the conductor pad.
5. The conductor pad of claim 1 , wherein the first convex segment has a first convex segment outermost edge at a distance H 1 from the horizontal axis, and wherein the second convex segment defines an outermost edge of the perimeter edge at a distance H 2 from the horizontal axis, wherein the distance H 2 is greater than the distance H 1 .
6. The conductor pad of claim 1 , wherein the first contact region and the first convex segment are at a proximal end of the conductor pad and the first convex segment extends in a direction away from the first contact region at an angle θ 1 , wherein θ 1 is a positive angle.
7. The conductor pad of claim 1 , wherein the second convex segment extends upward from the first non-convex segment in a direction away from the horizontal axis at an angle θ 2 , wherein θ 2 is between 0 and 45 degrees, inclusive.
8. The conductor pad of claim 1 , wherein the second convex segment defines an outermost edge of the perimeter edge at a distance H 2 from the horizontal axis, wherein the third convex segment has a third convex segment outermost edge at a distance H 3 from the horizontal axis, and wherein the distance H 2 is greater than the distance H 3 .
9. The conductor pad of claim 1 , wherein the fourth convex segment extends downward toward the second contact region at an angle θ 3 , wherein θ 3 is between 0 and 45 degrees, inclusive.
10. The conductor pad of claim 1 , wherein the first contact region and the second contact region are formed integrally with the body portion.
