Abstract

An LGA connector assembly (1) includes an LGA connector (2) and a generally rectangular pick up cap (3). The connector includes an insulative housing (21), a plurality of contacts (22) received in the housing, and a metal clip (25). The housing defines a cavity (210) for receiving an LGA central processing unit (CPU) therein. The clip is disposed on the housing to press the CPU upon the contacts. The pick up cap is generally rectangular, and has a plurality of clasps (307, 308) at two opposite ends thereof. The clasps snappingly clasp edges of the clip of the connector, thereby securely mounting the pick up cap onto the connector. The pick up cap has a flat top surface (300) to be engaged by a vacuum suction device. The LGA connector assembly thus can be moved to a desire location on a printed circuit board (PCB).

Claims

1. A land grid array (LGA) connector assembly, comprising:

an insulative housing defining a substantially rectangular cavity in a middle thereof, the cavity being adapted for receiving an electronic package therein;

a plurality of electrical contacts received in a portion of tie housing under the cavity;

a metal clip disposed on the housing to press the electronic package upon the contacts; and

a pick up cap attached to the clip, the pick up cap having a flat top surface to be engaged by a vacuum suction device.

21. The LGA connector assembly as claimed in claim 1, further comprising a metal frame in which the housing is received.

22. The LGA connector assembly as claimed in claim 21, further comprising a lever pivotally received in an end of the frame.

23. The LGA connector assembly as claimed in claim 22, wherein the clip is pivotably mounted to an opposite end of the frame for engaging with the lever.

24. The LGA connector assembly as claimed in claim 1, wherein said pick up cap has a clasp clasping a corresponding edge of the clip.

2-12. -12. (canceled)

13. An electrical connector assembly comprising:

an insulative housing subassembly defining a cavity for receiving an electronic package therein;

a plurality of contacts located mainly under the cavity for mechanically and electrically connecting the electronic package;

a metal clip moveable relative to the housing subassembly for allowing

installation of the electronic package in the cavity when said clip is in an open position or sealing of the electronic package in the cavity when said clip is in a closed position, wherein said clip does not provide a sufficiently large flat top surface thereon; and

a pick-up cap attached to at least one of said clip and said housing subassembly and substantially located on said clip, wherein said pickup cap provides a sufficiently large flat top surface thereon for suction by a vacuum suction device.

14. The assembly as claimed in claim 13, wherein said cap is attached to the clip.

15. The assembly as claimed in claim 13, wherein said clip defines a downwardly curved configuration for downwardly pressing said electronic package located in the cavity.

16. The assembly as claimed in claim 15, wherein said cap defines a convex configuration on the underside to be compliantly received within a concave space formed above the downwardly curved configuration of the clip.

17. The assembly as claimed in claim 13, wherein said clip is mounted to a frame of said housing subassembly, said frame surrounding said housing.

18. An electrical connector assembly comprising:

an insulative housing subassembly defining a cavity for receiving an electronic package therein;

a plurality of contacts located mainly under the cavity for mechanically and electrically connecting the electronic package;

a clip pivotally located on a top portion of the housing subassembly for

allowing installation of the electronic package in the cavity when said clip is in an open position or sealing of the electron package in the cavity when said clip is in a closed position; and

a pick-up cap for suction by a vacuum suction device, being disposed above the clip with provision of a sufficiently large planar top surface thereon, and fastened to at least one of said clip and said housing subassembly.

19. The assembly as claimed in claim 18, wherein said cap defines a convex configuration on the underside to be compliantly received within an upward concave space formed in the clip.

20. The assembly as claimed in claim 18, wherein said cap is attached to the clip.
