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.
Claims9
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.
