Abstract
Abstract A test socket for testing chips and chips on tape wherein the test socket is formed on a heat resistant dielectric film having contact pads and connector pads joined by metallic circuit traces and which film is wrapped on a compliant pad. The connector end of the tape is joined to a circuit board by a conductive tape and maintained in contact by the compliant pad. A frame registers the chip with the contact area of the tape.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
218 words
A socket connector for use in test and burn-in of integrated circuit devices having contact points, said connector comprising: a conductive metal layer beam tape having a central portion and end portions, said central portion of said beam tape defining a contact area having contact portions to contact the contact points of the integrated circuit device and a connector area at said end portions having spaced connector portions for connection to correspondingly spaced contacts on a circuit board, said beam tape having registration holes selectively positioned in relationship to said contact portions and said connector portions, and said beam tape being folded between said contact area and said connector area, a compliant elastomeric pad disposed between said contact area and said connector area for supporting said contact area and said connector area, frame means for supporting said pad and locating said connector area with said spaced connector portions positioned opposite to the contacts of a said printed circuit board and for locating an integrated circuit device to place the contact points on the contact portions of said contact area, said frame means including registration pins extending through said registraton holes, and means for pressing said integrated circuit device onto said contact area with the contact points engaging said contact portions against the resilient support of said elastomeric pad.
Claim 2
Dependent Claim
218 words
A socket connector for use in test and burn-in of integrated circuit devices having contact points, said connector comprising: a conductive metal layer beam tape having a central portion and end portions, said central portion of said beam tape defining a contact area having contact portions to contact the contact points of the integrated circuit device and a connector area at said end portions having spaced connector portions for connection to correspondingly spaced contacts on a circuit board, said beam tape having registration holes selectively positioned in relationship to said contact portions and said connector portions, and said beam tape being folded between said contact area and said connector area, a compliant elastomeric pad disposed between said contact area and said connector area for supporting said contact area and said connector area, frame means for supporting said pad and locating said connector area with said spaced connector portions positioned opposite to the contacts of a said printed circuit board and for locating an integrated circuit device to place the contact points on the contact portions of said contact area, said frame means including registration pins extending through said registraton holes, and means for pressing said integrated circuit device onto said contact area with the contact points engaging said contact portions against the resilient support of said elastomeric pad.
Claim 3
Dependent Claim
34 words
A socket connector according to claim 1 wherein a strip of tape having opposite surfaces, which is conductive through the tape between the surfaces, is applied over the connector area of said beam tape.
Claim 4
Dependent Claim
49 words
A socket connector according to claim 2 wherein said beam tape comprises a thin dielectric backing and on one surface a pattern of conductive strips defining circuit traces which strips are joined to individual crowns on the opposite surface of the tape defining said contact portions and connector portions.
Claim 5
Dependent Claim
50 words
A socket connector according to claim 1 wherein said frame means comprises a plate having a rectangular opening and a brace spanning said opening, said elastomeric pad being positioned about said brace to urge said connector area toward a said circuit board and said contact area, toward a said device.
Claim 6
Dependent Claim
34 words
A socket connector according to claim 4 wherein fastening means secure said frame means to a said printed circuit board with the elastomeric pad pressing said tape connector area toward said printed circuit board.
Claim 7
Dependent Claim
41 words
A socket connector according to claim 4 wherein said brace has pin means extending from opposite surfaces thereof and through said beam tape adjacent to said contact area and said connector area for registering said beam tape to said frame means.
Claim 8
Dependent Claim
38 words
A socket connector according to claim 5 wherein said pin means includes means for registering said frame means with a said circuit board for registering said connector area with a series of contacts formed on said circuit board.
Claim 9
Dependent Claim
77 words
A socket connector according to claim 7 wherein said means for pressing said integrated circuit device onto said contact area comprises a cover hinged to said base and formed to move from an open position to a closed mating position with said base to urge said beam tape contact area against said elastomeric pad for urging a said circuit device into intimate electrical contact therewith, and releasable latch means for holding said cover in said mating position.
Claim 10
Dependent Claim
31 words
A socket connector according to claim 8 wherein registration means afford alignment of a said circuit device with said contact area of said beam tape for making said electrical contact therewith.
