Abstract

A clip-type connector for electrically coupling a substrate with a device or another substrate is disclosed. An electrical connector comprises a top plate and a bottom plate. An array of contacts are on at least one of the top plate and bottom plate. A hinge is located between the top plate and the bottom plate such that the hinge mechanically connects the top plate to the bottom plate. A spring applying a force against the top and bottom plates.

First claim

What is claimed is:

1. An electrical connector, comprising:
a top plate, the top plate having a top surface and an opposite bottom surface;
a bottom plate, the bottom plate having a top surface and an opposite bottom surface, the top surface of the bottom plate facing the bottom surface of the top plate;
an array of contacts on at least one of the top plate and bottom plate, wherein the array of contacts extends from the top surface to the bottom surface of the at least one of the top plate and bottom plate;
a hinge between the top plate and the bottom plate, the hinge mechanically connecting the top plate to the bottom plate; and
a spring applying a force against the top and bottom plates.

2. The electrical connector of claim 1 , wherein the force draws an engaging region of the top plate toward an engaging region of the bottom plate.

3. The electrical connector of claim 1 , wherein the array of contacts comprises copper cylinders on a bump-on-flex cable.

4. The electrical connector of claim 1 , wherein the array of contacts is a spring-type contact.

5. The electrical connector of claim 4 , wherein the spring-type contact is a cantilever contact.

6. The electrical connector of claim 1 , wherein the spring is located in the hinge, forming a spring-loaded hinge.

7. The electrical connector of claim 1 , wherein the spring comprises a pair of linear springs between the top and bottom plates on either side of the hinge perpendicularly connected to the top and bottom plates.

8. The electrical connector of claim 1 , wherein the top plate comprises a top locking feature.

9. The electrical connector of claim 1 , wherein the bottom plate comprises a bottom locking feature.

10. The electrical connector of claim 1 , wherein the bottom plate comprises a stopping feature.

11. An electronic assembly, comprising:
a package comprising a die electrically coupled to a substrate, the substrate comprising a diving board that protrudes from an edge of the substrate;
an electrical connector electrically coupled to the substrate through the diving board, the electrical connector comprising:
a top plate, a bottom plate, an array of contacts on at least one of the top plate and bottom plate, a hinge between the top plate and the bottom plate, the hinge mechanically connecting the top plate to the bottom plate, and a spring applying a force against the top and bottom plates; and
a cable electrically coupled to the electrical connector, the electrical connector is electrically coupled to the substrate.

12. The electronic assembly of claim 11 , wherein the substrate is a package substrate.

13. The electronic assembly of claim 12 , wherein the diving board comprises an array of pads, each pad of the array of pads does not extend to an edge of the diving board.

14. The electronic assembly of claim 13 , wherein the edge of the diving board contacts a stopping feature on the electrical connector.

15. The electronic assembly of claim 11 , wherein the diving board comprises a locking key.

16. The electronic assembly of claim 15 , wherein the locking key is a notch formed at an edge of the diving board into which a locking feature on the electrical connector fits.

17. The electronic assembly of claim 11 , wherein the cable is a flex cable.

18. The electronic assembly of claim 17 , wherein the flex cable comprises an array of contacts on a first end of the flex cable.

19. The electronic assembly of claim 18 , further comprising a compliant mattress disposed behind the array of contacts and between the flex cable and at least one of the top and bottom plate.

20. A method of forming an electronic assembly, comprising:
providing a package comprising a die electrically coupled to a substrate, the substrate comprising a diving board that protrudes from an edge of the substrate;
providing an electrical connector comprising:
a top plate, a bottom plate, an array of contacts on at least one of the top plate and bottom plate, a hinge between the top plate and the bottom plate, the hinge mechanically connecting the top plate to the bottom plate, and a spring applying a force against the top and bottom plates;
applying force upon a non-engaging region of the electrical connector;
aligning the electrical connector and the diving board to one another; and
removing the force, causing electrical coupling between the electrical connector and the substrate.

21. The method of claim 20 , wherein the array of contacts do not travel on the substrate.

22. The method of claim 20 , wherein applying the force causes an engaging end of the electrical connector to open.

23. The method of claim 20 , wherein electrical coupling is created by a closing force generated by a spring in the electrical connector.

24. The method of claim 20 , wherein aligning the electrical connector includes inserting a locking feature into a locking key.

25. The method of claim 20 , wherein aligning the electrical connector includes the substrate contacting a stopping feature on the electrical connector.
