Abstract:
Embodiments that allow multi-chip interconnect using organic bridges are described. In some embodiments an organic package substrate has an embedded organic bridge. The organic bridge can have interconnect structures that allow attachment of die to be interconnected by the organic bridge. In some embodiments, the organic bridge comprises a metal routing layer, a metal pad layer and interleaved organic polymer dielectric layers but without a substrate layer. Embodiments having only a few layers may be embedded into the top layer or top few layers of the organic package substrate. Methods of manufacture are also described.
Abstract:
A circuit board with a heat-recovery function includes a substrate, a heat-storing device, and a thermoelectric device. The heat-storing device is embedded in the substrate and connected to a processor for performing heat exchange with the processor.

Abstract:
A surface mount electrical interconnect adapted to provide an interface between solder balls on a BGA device and a PCB. The electrical interconnect includes a socket substrate with a first surface, a second surface, and a plurality of openings sized and configured to receive the solder balls on the BGA device. A plurality of electrically conductive contact tabs are bonded to the first surface of the socket substrate so that contact tips on the contact tabs extend into the openings. The contact tips electrically couple with the BGA device when the solder balls are positioned in the openings. Vias are located in the openings that electrically couple the contact tabs to contact pads located proximate the second surface of the socket substrate. Solder balls are bonded to the contact pad that are adapted to electrically and mechanically couple the electrical interconnect to the PCB.
