Carrier tape

1. A carrier tape having pockets for carrying electronic components, the carrier tape comprising:

a longitudinally extending elevated central portion having a plurality of pockets formed therein and two side portions, each of the side portions is disposed on opposite sides of the elevated central portion and extending longitudinally therewith, wherein each of the two side portions is attached to the elevated central portion by an inclined portion such that the elevated central portion is higher than the two side portions when disposed in a flat configuration, and wherein each of the two side portions includes an adhesion zone that is spaced apart from the elevated central portion;

wherein each of the plurality of pockets includes at least one side walls that extends down from a top surface of the elevated central portion and is joined to a bottom wall and wherein the bottom wall of each of the pockets defines a reference plane.

2. The carrier tape of claim 1 , further comprising at least one row of advancement structures formed longitudinally along the side portion of the carrier tape.

3. The carrier tape of claim 1 , further comprising at a row of aligned advancement structures formed longitudinally along each side portion of the carrier tape.

4. The carrier tape of claim 1 , wherein the side portions are generally parallel with the bottom wall of each of the pockets.

5. The carrier tape of claim 1 , wherein the elevated central portion is generally parallel with the bottom wall of each of the pockets.

6. The carrier tape of claim 1 , wherein the side portions are disposed at a first reference height relative to the reference plane and the elevated central portion is disposed at a second reference height relative to the reference plane and wherein the second reference height is greater than the first reference height.

7. The carrier tape of claim 1 , wherein the elevated central portion comprises a plurality of plateau portions disposed between adjacent pockets within the elevated central portion and having a plateau surface and a pair of rail portions that extend longitudinally along the elevated central portion on either side of the pockets and having a rail surface.

8. The carrier tape of claim 7 , wherein the plateau surface and the rail surface are coplanar.

9. The carrier tape of claim 7 , wherein the plateau surface is higher than the rail surface.

10. A carrier tape having pockets for carrying electronic components, the carrier tape comprising:

a longitudinally extending central portion having a plurality of pockets formed therein and a plurality of elevated lip portions wherein the elevated lip portions are adjacent to at least a portion of each edge of each of the pockets are formed within the central portion and two side portions, each of the side portions is disposed on opposite sides of the central portion and extend longitudinally therewith, wherein each of the side portions includes an adhesion zone that is spaced apart from the central portion, the adhesion zone being adapted to adhere to a cover film;

wherein the pocket includes at least one side walls that extends down from a top surface of at least one of the elevated lip portions and is adjoined a bottom wall and wherein the bottom wall of the pocket defines a reference plane; and

wherein the side portions are disposed at a first reference height relative to the reference plane and the to surface of at least one of the elevated lip portions is disposed at a second reference height relative to the reference plane and wherein the second reference height is greater than the first reference height.

11. The carrier tape of claim 10 , wherein the elevated lip portions are discontinuous.

12. The carrier tape of claim 10 , wherein the elevated lip portions are continuous and completely surrounds the pockets disposed within the central portion of the carrier tape.
