Abstract:
A substrate for supporting a semiconductor chip has area array connectors on at least two surfaces to provide a large number of connectors to the chip. At least one contact on one surface is not connected to a contact on the other surface through the substrate. Carriers, such as printed circuit boards are mounted to the two surfaces.
Abstract:
A power interconnection system comprising a plurality of z-axis compliant connectors passing power and ground signals between a first circuit board to a second circuit board is disclosed. The interconnection system provides for an extremely low impedance through a broad range of frequencies and allows for large amounts of current to pass from one substrate to the next either statically or dynamically. The interconnection system may be located close to the die or may be further away depending upon the system requirements. The interconnection may also be used to take up mechanical tolerances between the two substrates while providing a low impedance. interconnect.
Abstract:
A processor mounted to a circuit board is provided with regulated voltage through lower-inductance circuit board traces by mounting a voltage regulator module for the processor, on the side of the circuit opposite to the processor. Current from the voltage regulator is provided to the processor by way of one or more conductors between the regulator and processor that extend through the circuit board from one side to the other. Inductance attributable to lead length is reduced by locating the voltage regulator close to its load. Circuit board space on the processor side of the circuit board is increased by moving the voltage regulator to the opposite side.

Abstract:
A power delivery device includes a socket to couple and deliver power to an electronic component. A voltage control sensor is coupled to the socket to sense an output voltage at the socket and to provide negative feedback control. An impedance of the socket and an associated baseboard is incorporated into the negative feedback control and may help compensate for voltage droop in the output voltage.
