Brief Patent Description - Full Patent Description - Patent Claims

The Patent Description & Claims data below is from USPTO Patent Application 20060216957, Integrated circuit package socket and socket contact.

1. An integrated circuit (IC) package socket, comprising: a package receiving portion including a package surface and an opposite contact pad surface; and an array of contact pins arranged in the package receiving portion where each contact pin is formed from a single piece of conductive material, each contact pin has a central mounting portion and first and second ends extending from the central mounting portion, where the first and second ends are independently resilient, where a first portion of the contact pin including the first end extends from the central mounting portion away from the package surface, around an acutely bent angle and then toward the package surface, and where a second portion of the contact pin including the second end extends away from the contact pad surface, around an acutely bent angle, and then toward the contact pad surface.

2. The socket of claim 1 where a contacting portion of the first and second ends of each contact pin are sharply shaped to penetrate oxide and contamination on a contact area of a package and contact pad.

3. The socket of claim 1 where the package receiving portion includes a Ball Grid Array package receiving structure.

4. The socket of claim 1 where the package receiving portion includes a Land Grid Array package receiving structure.

5. The socket of claim 1 comprising an array of support structures to support the array of contact pins.

6. The socket of claim 1 where the conductive material of each contact pin is a Beryllium Copper alloy.

7. The socket of claim 1 where the socket is mounted on a printed circuit board having corresponding contact pads.

8. The socket of claim 1 where the socket is a plurality of sockets mounted on a single board to perform one of burn-in, testing, and programming of IC packages.

9. The socket of claim 1 where the socket is mounted to a board.

10. A method of electrically connecting an integrated circuit (IC) package to a contact pad on a circuit board, comprising: mounting an array of contact pins in a socket; mounting the socket on the circuit board; contacting the contact pad on the circuit board with a sharp first end of each of the contact pins, laterally swiping the contact pad with the sharp first end of each contact pin; and contacting an array of package lands on the IC package with a sharp second end of each of the contact pins, laterally swiping each package land with the sharp second end of each corresponding contact pin; where the first end of a contact pin is independently resilient from the second end of the contact pin; where a first portion of one of the contact pins including the first sharp end extends from a central mounting portion away from the package land, around an acutely bent angle and then toward the package land; and where a second portion of the one contact pin including the second sharp end extends away from the contact pad, around an acutely bent angle, and then toward the contact pad.

11. (canceled)

12. The method of claim 10 where each of the contact pins is formed from a single piece of conductive material.

13. The method of claim 10 where mounting the array of contact pins in the socket includes removably mounting each contact pin to a pin support.

14. The method of claim 13 where removably mounting each contact pin to the pin support includes removably mounting a center potion of each contact pin to the pin support.

15. The method of claim 10 where mounting the socket on the circuit board includes mounting the socket on a printed circuit board.

16. The method of claim 10 comprising performing any one of burn-in, testing, and programming the IC package.

17. The method of claim 10 where mounting the socket on the circuit board includes mounting the socket on a motherboard.

18. (canceled)
