Abstract

A stretch release adhesive is disclosed. The stretch release adhesive can be used for extracting an electrical component from an interior surface of a housing of a mobile computing device. The stretch release adhesive can have a double-sided adhesive body configured to adhere the component to the interior surface of the housing. A portion of the double-sided adhesive body is configured to extend out from between the electrical component and the interior surface of the housing to provide a graspable portion. When the stretch release adhesive is adhered between the electrical component and the internal surface of the housing, the stretch release adhesive can receive a pulling force at the graspable portion. If pulled with enough force, the stretch release adhesive will extend outwardly from between the electrical component and the internal surface of the mobile computing device, then completely release the electrical component from the mobile computing device.

First claim

What is claimed is:

1. A stretch release adhesive configured to both secure a component to an interior surface of a housing and to extract the component from the interior surface of the housing, the stretch release adhesive comprising:
a double-sided adhesive body configured to adhere the component to the interior surface of the housing, and having a leg at a distal end of the double-sided adhesive body for placement between the component and the interior surface of the housing; and
a graspable portion that is formed at an opposite distal end of the double-sided adhesive body relative to the leg and extends away from the double-sided adhesive body in a non-parallel direction relative to the leg.

2. The stretch release adhesive of claim 1 , wherein the double-sided adhesive body includes a secondary leg that extends parallel to the leg and is separated from the leg by a gap, and a length of the gap extends in a different direction than the graspable portion.

3. The stretch release adhesive of claim 1 , wherein a distance from which the graspable portion extends from the double-sided adhesive body is less than a width of the at least one leg.

4. The stretch release adhesive of claim 1 , wherein the graspable portion includes a hole for providing a means to further grip the graspable portion, and an edge of graspable portion at least partially defines an edge of the opposite distal end of the double-sided adhesive body.

5. The stretch release adhesive of claim 4 , further comprising:
a pull tab liner disposed over the graspable portion, wherein the pull tab liner includes a liner hole that at least partially overlaps the hole of the graspable portion.

6. A stretch release adhesive, comprising:
a double-sided adhesive body;
two legs formed at a distal end of the double-sided adhesive body;
a gap between the two legs and extending across a majority of a length of the two legs; and
a graspable portion that is formed to the double-sided adhesive body and extends away from the double-sided adhesive body in a non-parallel direction relative to the two legs.

7. The stretch release adhesive of claim 6 , wherein the graspable portion comprises a non-sticky surface that includes a hole.

8. The stretch release adhesive of claim 6 , wherein an edge of graspable portion at least partially defines an edge of the distal end of the double-sided adhesive body.

9. The stretch release adhesive of claim 6 , wherein the gap extends in a different direction than the graspable portion extends from the double-sided adhesive body.

10. The stretch release adhesive of claim 6 , wherein a distance from which the graspable portion extends from the double-sided adhesive body is less than a width of the two legs.

11. The stretch release adhesive of claim 6 , further comprising:
a first pull tab liner disposed over the two legs of the double-sided adhesive body, and
a second pull tab liner disposed over the graspable portion.

12. The stretch release adhesive of claim 11 , wherein the second pull tab liner includes an aperture that overlaps a hole in the graspable portion.

13. The stretch release adhesive of claim 6 , wherein the graspable portion comprises siliconized polyethylene terephthalate (PET).

14. A method for producing a stretch release adhesive configured to both secure a component to an interior surface of a housing and to extract the component from the interior surface of the housing, the method comprising:
placing the stretch release adhesive between the component and the interior surface of the housing, the stretch release adhesive comprising a double-sided adhesive body having a leg, and a graspable portion formed at a distal end of the double-sided adhesive body opposite the leg and extending away from the double-sided adhesive body in a non-parallel direction relative to the leg.

15. The method of claim 14 , further comprising:
removing a liner from two sides of the double-sided adhesive body before placing the stretch release adhesive between the component and the interior surface of the housing.

16. The method of claim 14 , wherein placing the stretch release adhesive between the component and the interior surface of the housing further comprises extending the double-sided adhesive body over a majority of a surface of the component.

17. The method of claim 14 , wherein the pulling force is directed by a structure that is coupled to a platform on which the component is secured.

18. The method of claim 17 , wherein the structure is a roller structure.

19. The method of claim 17 , wherein the structure is a blade structure.

20. The method of claim 19 , wherein an outer surface of the blade structure comprises a low friction material.
