Abstract

An area array connector (32,42,50) for electrically interconnecting two electronic devices is disclosed. The connector (32,42,50) includes a plurality of contact elements (10) having parallel cantilevered contact fingers (18) extending obliquely outwardly from a plate (20) for one embodiment, a laminate (32) is formed by securing the contact elements (10) to a dielectric (26) having windows (28) through which the fingers (18) extend. The laminate (32) can then be fixed to a device such as a circuit board (40) to form another form of a connector (42) and further, the dielectric (26) can be removed to form yet another form of connector (50).

Claims

1. An electrical area array connector for use in interconnecting first and second electronic devices, each having an array of contact pads disposed on a planar surface thereof, an array of contact elements each including a plate portion electrically and mechanically attached to the contact pad of the second device and at least one contact spring finger extending freely and obliquely relative to the plane of the plate portion an second element to resiliently engage the contact pad of the first device and provide an interconnection of the contact pads of the first and second devices.

2. The connector of claim 1 wherein the said contact elements each include a pair of contacts springs.

3. The connector of claim 1 wherein the said plate portion is soldered to the contact pad of the second device to effect the electrical and mechanical connection therewith.

4. The connector of claim 1 further including a plastic sheet having holes therein on centers compatible with the array of pads of the firs and second devices with the holes having a geometry to receive the contact finger inserted therethrough and with the contacts attached to said sheet to facilitate mounting of the contacts on the second device.

5. An electrical area array connector for use in interconnecting electronic devices, comprising a plurality of contact elements having a cantilevered contact finger extending obliquely outwardly from one side of a plate wherein each contact element includes a pair of parallel cantilevered contact fingers.

6. An electrical area array connector for use in interconnecting electronic devices, comprising a plurality of contact elements having a cantilevered contact finger extending obliquely outwardly from one side of a plate wherein each contact element includes a pair of legs extending outwardly from an opposite side of said plate.

7. A connector of a type adapted to interconnect electrical devices each having planar surfaces with contact pads thereon arranged in an array on given centers including an array of contacts, one for each contact pad of one of the devices, each contact having a flat plate portion electrically and mechanically attached to each pad of the one device with a contact spring finger extending from the plate portion at an angle to the surface of one of the devices adapted to be deflected by the devices being driven relatively together to interconnect the pads of the one device to the pads of the other device.

8. The connector of claim 7 wherein the contact includes a pair of spring fingers with the ends thereof effecting such interconnection between pads.

9. The connector of claim 7 wherein the said plate portions are soldered to the pads of the one device.

10. The connector of claim 7 wherein there is included a plastic sheet with the said contacts laminated thereto on a given centers prior to soldering of the plate to the pads.
