Abstract
Abstract A carrier for making electrical connection with a microelectronic device without bonding the device to the carrier is disclosed. The carrier is designed to accommodate a device such as, but not limited to, a magnetic bubble domain memory chip. The circuit board and keeper board are joined by a hinge having tension means to readily permit opening and locking of the carrier. When the carrier is in the open position, a device is positioned in the carrier. By locking the carrier, the device is secured and the required electrical connection is made between the carrier and the device. The carrier can now be connected to a test fixture for evaluating the electrical characteristics of the chip without bonding any leads or the carrier may be utilized in a system as an integral part of that system.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
76 words
An apparatus for supporting a device comprising: a first board having at least one cavity for accommodating said device; at least one electrical conductor disposed on said first board and extending over said cavity to form beam lead interconnections; resilient means formed to fit around the inner surface of said cavity for applying force to said beam lead interconnections; a second board; hinge means joining said first and second boards; and locking means for said boards.
Claim 2
Independent Claim
76 words
An apparatus for supporting a device comprising: a first board having at least one cavity for accommodating said device; at least one electrical conductor disposed on said first board and extending over said cavity to form beam lead interconnections; resilient means formed to fit around the inner surface of said cavity for applying force to said beam lead interconnections; a second board; hinge means joining said first and second boards; and locking means for said boards.
Claim 3
Dependent Claim
18 words
The apparatus recited in claim 1 wherein said first board and said second board have substantially similar configurations.
Claim 4
Dependent Claim
30 words
An apparatus as recited in claim 1 including a plurality of electrical conductors on said first board which flare out to form a connector end for inserting into test apparatus.
Claim 5
Dependent Claim
32 words
An apparatus as recited in claim 1 wherein said resilient means is formed from rubber material and is laminated between a top layer of said first board and said beam lead interconnectors.
Claim 6
Dependent Claim
29 words
An apparatus as recited in claim 1 wherein said hinge is formed from a separate polyimide film and is connected opposite the connector at the end of said boards.
Claim 7
Dependent Claim
48 words
An apparatus as recited in claim 1 wherein said locking means of said boards includes a first pin adjacent said cavity and a second pin located adjacent the connector end of said second board, both pins of said second board fitting in corresponding apertures in said first board.
Claim 8
Dependent Claim
30 words
An apparatus as recited in claim 1 wherein electrical contact is made when said boards are locked and said resilient means compresses said beam leads in contact with said device.
Claim 9
Dependent Claim
27 words
An apparatus as recited in claim 1 including said device wherein said apparatus is installed in a system to function as an integral part of that system.
Claim 10
Dependent Claim
17 words
An apparatus as recited in claim 1 wherein said beam lead interconnectors are formed from beryllium copper.
Claim 11
Independent Claim
136 words
An apparatus for testing and carrying non-beam leaded devices comprising: a first board having at least one cavity for accommodating said device and at least one electrical conductor disposed on said first board and extending over said cavity to form beam lead interconnectors; resilient means formed on the inner surface of said cavity said resilient means inlaid over said beam leads and covered by an epoxy layer for compressing said beam lead interconnections; a second board having at least one cavity; connecting means for said first and second boards; aligning means for said first and second boards; tension means on said first board for placing said beam lead interconnects in electrical contact with the leads of said device; and locking means for maintaining electrical contact with said beam leads interconnection and the leads of said device.
Claim 12
Independent Claim
136 words
An apparatus for testing and carrying non-beam leaded devices comprising: a first board having at least one cavity for accommodating said device and at least one electrical conductor disposed on said first board and extending over said cavity to form beam lead interconnectors; resilient means formed on the inner surface of said cavity said resilient means inlaid over said beam leads and covered by an epoxy layer for compressing said beam lead interconnections; a second board having at least one cavity; connecting means for said first and second boards; aligning means for said first and second boards; tension means on said first board for placing said beam lead interconnects in electrical contact with the leads of said device; and locking means for maintaining electrical contact with said beam leads interconnection and the leads of said device.
