Abstract:
1. A compliant leaded interposer for resiliently attaching and electrically connecting a ball grid array package to a circuit board, the ball grid array package having solder balls arranged in a solder ball pattern, the compliant leaded interposer comprising: a substrate having a top surface and a bottom surface; a plurality of pads positioned substantially on the top surface of the substrate and arranged in a predetermined pattern substantially corresponding to the solder ball pattern, each of the plurality of pads being associated with one of the solder balls, each of the plurality of pads being at least partially embedded into the substrate; and a plurality of pins positioned substantially perpendicular to the top surface of the substrate and extending through the substrate and the plurality of pads, the plurality of pins being arranged in the predetermined pattern with each of the plurality of pins being associated with one of the solder balls, each of the plurality of pins having a first end configured to extend a first distance beyond the top surface of the substrate and a second end configured to extend a second distance beyond the bottom surface of the substrate; wherein the interposer is configured to attach the ball grid array package to the circuit board such that each of the solder balls contacts at least a portion the first end of one of the plurality of pins and at least a portion of one of the plurality of pads and such that the second end of each of the plurality of pins attaches to an associated contact on the circuit board.
