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: 11
Claim 1
Independent Claim
194 words
A socket connector for use in test and burn-in of integrated circuit devices having contact points, said connector comprising a frame for locating an integrated circuit device and electrical connections for contact with the contact points of a said integrated circuit device, characterized by the feature that said electrical connections comprise: a conductive metal layer beam tape, one 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 having spaced connector portions for connection to correspondingly spaced contacts on a circuit board, 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, that said frame includes means for locating said connector area with respect to the contacts of a printed circuit board and means for locating the contact points on an integrated circuit device with respect to said contact area, and that means are provided for pressing an integrated circuit device onto said contact area against the resilient support of said elastomeric pad.
Claim 2
Dependent Claim
194 words
A socket connector for use in test and burn-in of integrated circuit devices having contact points, said connector comprising a frame for locating an integrated circuit device and electrical connections for contact with the contact points of a said integrated circuit device, characterized by the feature that said electrical connections comprise: a conductive metal layer beam tape, one 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 having spaced connector portions for connection to correspondingly spaced contacts on a circuit board, 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, that said frame includes means for locating said connector area with respect to the contacts of a printed circuit board and means for locating the contact points on an integrated circuit device with respect to said contact area, and that means are provided for pressing an integrated circuit device onto said contact area against the resilient support of said elastomeric pad.
Claim 3
Dependent Claim
37 words
A socket connector according to Claim 1 characterized in that a strip of tape having opposite surfaces, which is conductive through the tape between said opposite surfaces, is applied over the connector area of said beam tape.
Claim 4
Dependent Claim
53 words
A socket connector according to Claim 1 or 2 characterized in that 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
53 words
A socket connector according to Claim 1 characterized in that said frame 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 integrated circuit device.
Claim 6
Dependent Claim
42 words
A socket connector according to Claim 4 characterized in that 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.
Claim 7
Dependent Claim
33 words
A socket connector according to Claim 4 characterized in that fastening means secure said frame to a said circuit board with the elastomeric pad pressing said tape connector area toward said circuit board.
Claim 8
Dependent Claim
39 words
A socket connector according to Claim 5 characterized in that said pin means includes means for registering said frame with a said circuit board for registering said connector area with a series of contacts formed on said circuit board.
Claim 9
Dependent Claim
83 words
A socket connector according to claim 7 characterized in that said means for pressing said integrated circuit device onto said contact area comprises a cover hinged to said frame and said cover is formed to move from an open position to a closed mating position with said frame to urge said beam tape contact area against said elastomeric pad for urging a said integrated circuit device into intimate electrical contact therewith, and releasable latch means for holding said cover in said mating position.
Claim 10
Dependent Claim
34 words
A socket connector according to claim 3 characterized in that registration means afford alignment of a said integrated circuit device with said contact area of said beam tape for making said electrical contact therewith.
Claim 11
Dependent Claim
66 words
A socket connector according to claim 9 characterized in that said registration means comprises a brace positioned on said frame, that said elastomeric pad is positioned about said brace to urge said connector area toward a said circuit board, and that said registration means comprises pins means extending from said brace, through said pad and said beam tape, for engagement with a said integrated circuit device.
