Abstract: The present invention is a cost effective, reworkable, LGA-based interconnection for use between two circuit members such as a ceramic module and an FR4-based system board. The resilient contact members allow the reliable interconnection of two circuit members, even though the circuit members may have significantly different CTEs and have interconnections where the distance from neutral point is great enough to crack BGA or CGA solder connections. For factory reworkable applications, the ends of the contact members are semi-permanently attached to both the module and the system board. For certain field separable applications, semi-permanently attaching only one of the ends of an LGA to either the module or the system board provides increased reliability.

Abstract: The present invention provides a carrier that provides improved retention to the individual contact elements resulting in LGA interposer connectors with improved manufacturability, reliability and more uniform mechanical and electrical performance. In one embodiment, the carrier, which includes upper and lower sections of dielectric material with an adhesive layer in between, includes a plurality of openings, each of which may contain an individual contact element. During assembly of the connector, once the contact elements are inserted, the adhesive layer is reflowed, thereby allowing the carrier to capture the location of the contact elements both with respect to each other as well as to the carrier. Alternately, the carrier may be implemented in a fashion that, while not including an adhesive layer to be reflowed, still provides improved retention of the individual contact elements. These embodiments may by easier to assemble, and less expensive to manufacture, especially in high volumes. Description of the processes to assemble the carrier and overall connector are also disclosed.
