Abstract

An integrated circuit (IC) carrier having uniform conductivity and the ability to securely hold an IC in a predetermined position within the carrier is disclosed. The IC is securely held inside a closed enclosure without using the IC leads to support the IC. Additionally, a viewing window which allows the reading of information printed on the IC from outside the closed enclosure is disclosed. The enclosure is formed as a one-piece object which additionally includes a living hinge, a latching system, structure which aids stacking, and structure which facilitates opening of the enclosure by automated means.

Claims

1. A carrier having a closed mode for housing an integrated circuit having conductive leads attached to a rigid body, said carrier comprising:

(a) an enclosure having a top section and having a bottom section;

(b) means for electrically connecting said enclosure top and bottom sections together;

(c) means for maintaining said enclosure top and bottom sections in the closed mode; and

(d) means for holding the integrated circuit rigid body inside said enclosure between said top and bottom sections so that the conductive leads are unsupported by the carrier.

2. A carrier as claimed in claim 1 wherein said top section, said bottom section, and said connecting means are together formed into a one-piece object.

3. A carrier as claimed in claim 2 wherein said one-piece object is constructed from an antistatic material.

4. A carrier as claimed in claim 2 wherein said connecting means is a living hinge.

5. A carrier as claimed in claim 1 wherein the rigid body has information thereon, and wherein said carrier additionally comprises means, integral with said bottom section, for displaying the integrated circuit rigid body so that information printed thereon is observable from outside said enclosure.

6. A carrier as claimed in claim 1 wherein said holding means comprises:

(a) A holding pedestal located within said enclosure top section; and

(b) an integrated circuit retainer having a supporting lip, said retainer located within said enclosure bottom section so that said enclosure in the closed mode compresses the integrated circuit rigid body between said holding pedestal and said retainer supporting lip by spring action of said enclosure.

7. A carrier as claimed in claim 6 wherein:

(a) said enclosure bottom section additionally includes a floor; and

(b) said integrated circuit retainer additionally includes;

(1) an integrated circuit retaining pedestal having a base and a platform, the base being attached to the interior of said floor, said retaining pedestal extending toward the interior of said enclosure and terminating in the pedestal platform, and

(2) an integrated circuit anchoring wall having first and second edges, said anchoring wall first edge being attached to said retaining pedestal platform, said anchoring wall extending toward said floor, and said retainer supporting lip being attached to said anchoring wall second edge and being substantially parallel to said floor.

8. A carrier as claimed in claim 1 additionally comprising means, integral with the exterior of said enclosure, for aiding the stackability of the carrier by providing structure which mates with corresponding aiding means of other of said enclosures.

9. A carrier for a static sensitive device having a rigid body, said carrier comprising:

(a) an enclosure top section having surfaces constructed from an antistatic material;

(b) an enclosure bottom section having surfaces constructed from an antistatic material;

(c) an enclosure hinge constructed from an antistatic material, said hinge connecting said top section to said bottom section;

(d) means for latching said bottom section to said top section; and

(e) means, integral with one of said top and bottom section surfaces, for holding the device rigid body between said top and bottom sections so that the rigid body contacts said top and bottom section surfaces.

10. A carrier as claimed in claim 9 wherein said top section, said bottom section, and said hinge are together formed into a one-piece object.

14. A carrier as claimed in claim 9 wherein the device rigid body has information thereon, and wherein the carrier additionally comprises means, integral with said bottom section, for displaying the device rigid body so that information on the rigid body is observable from outside the carrier.

15. A carrier as claimed in claim 9 additionally comprising means, integral with the exterior of said top and bottom sections, for aiding the stackability of the carrier by providing structure which mates with corresponding aiding means of other of said bottom and top sections respectively.

11. A carrier for a static sensitive device having a rigid body and conductive leads attached to the rigid body, said carrier comprising:

(a) An enclosure top section constructed from an antistatic material;

(b) an enclosure bottom section constructed from an antistatic material;

(c) an enclosure hinge constructed from an antistatic material, said hinge connecting said top section to said bottom section;

(d) means for latching said bottom section to said top section; and

(e) means, integral with one of said top section and said bottom section, for holding the device rigid body between said top and bottom sections so that the rigid body contacts said top and bottom sections and the conductive leads are isolated from contact with the carrier.

12. A carrier as claimed in claim 11 wherein the carrier has a closed mode and wherein said holding means comprises:

(a) a holding pedestal located within said enclosure top section; and

(b) an integrated circuit retainer having a supporting lip, said retainer located within said enclosure bottom section so that the carrier in the closed mode compresses the device rigid body between said holding pedestal and said retainer supporting lip by spring action between said enclosure top and bottom sections.

13. A carrier as claimed in claim 12 wherein:

(a) said enclosure bottom section additionally includes a floor; and
