Abstract

An apparatus and method allowing the leads of an integrated circuit (IC) package to provide the electrical interface between an IC die housed within the IC package and a card connector of an IC card that is to be inserted into a host data processing system. The present invention comprises an IC package housed within a card casing to form an IC card, with the leads from the IC package providing the electrical interface between the IC card connector and the IC package. The IC card connector then provides the electrical interface between the IC card and the data processing system. The present invention eliminates a need for both a printed circuit board (PCB) and the soldering step of coupling the IC package to the PCB.

Claims

1. An integrated circuit (IC) card for use in a data processing device, comprising:

an IC package having multiple leads extending from said package;

a casing that encases said package; and

,

a connector residing within said casing, said connector providing an electrical interface between the leads of said IC package and said data processing device, such that when said IC package is inserted into said casing said leads contact said connector without the use of a printed circuit board.

2. The IC card of claim 1, said casing having an upper surface with an upper opening and a bottom surface with a bottom opening, wherein said IC package is inserted into said casing through said bottom opening, and said data processing device and said connector make said electrical interface through said upper opening.

3. The IC card of claim 2 wherein said casing has at least one stop at said bottom opening such that when said IC package is fully inserted into said casing, said stop holds said IC package securely within said casing.

4. The IC card of claim 1, wherein the IC package comprises:

an IC die coupled to a housing;

a plurality of leads on a surface of the housing, the plurality of leads coupled to the IC die, and extending from the housing, to couple the IC package to the casing.

5. The IC card of claim 4, wherein the plurality of leads comprise bump leads.

6. An integrated circuit (IC) card for use in a data processing device, comprising:

a connector having multiple connector contacts residing therein;

an IC package having multiple leads extending from said IC package, said IC package coupled to said connector such that said leads contact said connector contacts without the use of a printed circuit board and said connector contacts provide an electrical interface between said IC package and said data processing device;

a casing, said casing coupled to said connector such that said IC package is encased therein.

7. The IC card of claim 6 wherein said casing has a front edge with a first stop on said front edge and said connector has a back edge with a second stop on said back edge, such that when said casing is coupled to said connector said first and said second stops securely hold said casing and said connector together.

8. The IC card of claim 6, wherein the IC package comprises:

an IC die coupled to a housing;

a plurality of leads on a surface of the housing, the plurality of leads coupled to the IC die, and extending from the housing, to couple the IC package to the casing.

9. The IC card of claim 7, the casing having an upper surface with an upper opening and a bottom surface with a bottom opening, wherein said IC package is inserted into said casing through said bottom opening, and said data processing device and said connector make said electrical interface through said upper opening.

10. The IC card of claim 9, wherein the first stop and the second stop are at the front edge and the back edge of the bottom surface, such that the first stop and second stop hold the IC package securely within the casing.

11. A method of assembling an integrated circuit (IC) card for use in a data processing device, comprising:

providing a connector having multiple connector contacts residing therein;

providing an IC package having multiple leads extending therefrom;

inserting said IC package into connector such that said leads contact said connector contacts without the use of a printed circuit board and said connector contacts provides an electrical interface between said IC package and said data processing device;

providing a casing; and

,

coupling said casing to said connector such that said package is encased therein.

12. The method of claim 11 wherein providing a casing and providing a connector further include providing a casing having a front edge with at least one stop on said front edge and providing a connector having a back edge with at least one stop on said back edge, and the coupling said casing further includes coupling said casing to said connector such that said first and said second stops securely hold together said casing and said connector.

13. The method of claim 12, wherein the casing is provided with a bottom with a front edge and a back edge, the casing having an upper surface with an upper opening and a bottom surface with a bottom opening;

and

inserting the IC package is into said casing through said bottom opening, and said data processing device and said connector make said electrical interface through said upper opening.

14. The method of claim 13, further comprising:

holding the IC package securely within the casing using a stop at the bottom opening such that when the IC package is fully inserted into the casing, the stop holds the IC package securely within the casing.

15. A casing for an integrated circuit (IC) package comprising:

an upper surface and an upper opening; and

a bottom surface with a bottom opening;

a connector to provide an electrical interface between the IC package and another device, such that the connector provides an electrical interface between said IC package and another device without the use of a printed circuit board.

16. The casing of claim 15, wherein a plurality of leads of the IC package are coupled to one end of the connector, and the other device is coupled to the other end of the connector.

17. The casing of claim 16, wherein the plurality of leads comprise bump leads.

18. The casing of claim 15, wherein the IC package is inserted into the casing through the bottom opening.

19. The casing of claim 15, wherein an electrical contact between the IC package and the other device is made through the upper opening of the casing.

20. The casing of claim 15, further comprising:

a stop at the bottom opening such that when the IC package is fully inserted into the casing, the stop holds the IC package securely within the casing.
