摘要:
A method and system for creating a stock index for a group of investment management companies is disclosed. The method may include obtaining first trade information for each security representative of the group of investment management companies during a first time period, aggregating the first trade information for a predetermined time period, storing the aggregated first trade information, calculating from the aggregated first trade information an index for the group of investment management companies, determining a standardized measure of the index based on the aggregated first trade information obtained in the first time period, and periodically recalculating the index based on second trade information for each security representative of the group of investment management companies during a second time period.

摘要:
A method and apparatus for interconnecting an electronic module to a substrate through resilient wire conductors in an interposer arrangement. A carrier layer of insulating material with an array of apertures, arranged to align with both the electrical pads on an electronic module and electrical contacts on a substrate, each hold, for example, a resilient wadded wire connector. Each connector extends through the aperture provided and beyond the upper and lower surfaces of the carrier layer. Each resilient wadded wire connector and aperture is encapsulated with a elastomeric insulating material sufficiently deformable so as to allow said resilient wadded wire connector to deform upon application of a normal force from each side tending to depress the connector into its aperture. The encapsulation prevents loss or smear of a wadded wire connector when handling.

摘要:
A method and apparatus for electrically connecting two substrates using resilient wire bundles captured in apertures of an interposer by a retention film. The interposer comprises an electrically non-conductive carrier having two surfaces and apertures extending from surface to surface. A resilient wire bundle is disposed in each aperture. An electrically non-conductive retention film is associated with one or both surfaces of the carrier and has an orifice overlying each aperture. The width of each orifice is smaller than that of the underlying aperture to thereby enhance retention of the resilient wire bundle within the aperture. Pin contacts of one or both of the substrates make electrical contact with the resilient wire bundles by extending through the orifices of the retention film and partially through the apertures. In one embodiment, the interposer is a land grid array (LGA) connector that connects an electronic module and a printed circuit board (PCB).

摘要:
An electronic module and a method of assembling the electronic module. A circuit board is connected to a chip substrate by an array of connectors, and a base member is on the side of the circuit board away from the chip substrate and connector array. An elastomeric structure is placed between the circuit board and the base member. The elastomeric structure has voids between a first defining plane adjacent the circuit board and a second defining plane adjacent the base member, with the voids adapted to permit local deformation of elastomeric material in the structure. The method includes applying a compressive force between the circuit board and base member to at least partially compressing the elastomeric structure to improve load equalization on the circuit board.
摘要:
An interposer comprising a non-conductive carrier sheet with a pre-arranged pattern of conductive interconnect members positioned therethrough and formed from an elastomeric thermoplastic with suspended spherical and non-spherical conductive particles. The non-spherical conductive particles of the present invention are positioned, substantially perpendicularly to and partially through the contact faces of the interconnect member, thereby resulting in higher conductivity and efficiency. The interposer is formed by a mold comprising two sections with first and second sets of vias formed in the first and second mold sections, respectively, which permit the injected elastomer mixture to flow completely through the mold cavity and thereby aligns the non-spherical conductive particles. The exit side of the mold is further contacted by support posts of a separable mold interface creating a network of vent passages for venting of air and the elastomer mixture, resulting in less pressure within the mold and less mold flash.
