Abstract: A semiconductor die carrier includes a housing that defines a cavity for holding one or more semiconductor dies, electrically conductive leads, and a cover plate having an aperture formed therethrough. The housing includes insulative side walls and a end plate joined to the side walls. The side walls and the end plate may be molded together as a one-piece unit. One or more of the side walls includes openings for receiving the leads so that an internal lead section extends within the cavity and an external lead section extends from the side walls external of the housing. The side walls may include a recess for receiving the cover plate. The aperture in the cover plate allows a semiconductor die held in the housing to be exposed to the environment.

Abstract: An integrated module includes a connector for detachable connection to a signal source, with the connector having internal electrically conductive pins, and a housing defining a cavity for holding at least one semiconductor die. The housing includes side walls and an end plate joined to the side walls. Electrically conductive leads extend through at least one of the side walls with each of the leads including an internal lead section extending within the cavity and an external lead section extending externally of the cavity through at least one side wall. One of the side walls of the housing includes a portion that is attached to the connector, with the side walls and a bottom part of the connector being formed as one integrally molded part or as two separate parts that are joined together using processes such as ultrasonic welding.

Abstract: A system for housing telecommunications equipment includes a plurality of vertically disposed chassis, each chassis having a top that is substantially closed, two sides, two ends, and a base, wherein the top of each chassis is adapted to receive the base of an adjacent chassis. At least one vent is formed in each chassis adjacent the base for allowing air to enter the chassis, and at least one of the ends and one of the sides of the chassis are formed such that air may exit the chassis. The vent is disposed between the base and a portion of the chassis selected from the group consisting of either of the ends and either of the sides, and the vent is nonplanar in relation to that portion. More specifically, the chassis may be vertically disposed with substantially zero gap, and the vent member may be either an angled vent member or a notched vent member.
Abstract: A multi-chip module includes a housing having insulative side walls and an end plate, conductive leads extending from the side walls, integrated circuit (IC) dies mounted to the end plate, and one or more interconnect dies mounted to the end plate. The end plate is made from a heat sink material, such as copper. Each interconnect die is positioned between a pair of the IC dies. Electrically conductive material connects the IC dies to the interconnect die, connects the IC dies to the conductive leads, and connects the interconnect dies to the conductive leads. The interconnect dies function to interconnect the IC dies and to interconnect the IC dies to the conductive leads. The interconnect die may be embodied by wiring layers formed on a silicon substrate.

Abstract: An electrical connector includes a male connector and a female connector. The female connector includes a female connector housing and a plurality of female contact pins. The female contact pins includes a contact portion, a stabilizer portion, and a tail portion. The contact portion extends from the stabilizer portion at an angle. A lateral distance spanned by the angled contact portion is substantially the same as or less than the width of the stabilizer portion in the same direction. The female contact pins are arranged on the female connector housing in clusters of four. The clusters are arranged in rows such that each pair of rows defines five rows of female contact pins. The male connector includes a male connector housing and a plurality of male contact pins. The male connector housing has a plurality of buttresses extending therefrom. The male contact pins are arranged on the male connector housing to correspond to the arrangement of female contact pins.

Abstract: An electrical connector includes a projection-type interconnect component and a receiving type interconnect component. The projection-type interconnect component includes an insulative buttress and a plurality of electrically conductive contacts. The contacts are spaced from each other around a circumference of the insulative buttress. The receiving-type interconnect component is adapted for receiving the projection-type interconnect component. The receiving-type interconnect component includes a plurality of flexible, electrically conductive contacts and a spacer movable relative to the flexible contacts. The spacer at least partially flexes the flexible contacts when the spacer is in a first position. The insulative buttress of the projection-type interconnect component displaces the spacer of the receiving-type interconnect component when the projection-type interconnect component is received by the receiving-type interconnect component.
Abstract: A lead insertion machine includes a substrate supply, a conductive lead supply, and an lead insertion mechanism. The conductive leads are inserted into lead passages formed in side walls of the substrate. Also disclosed is a method of manufacturing a semiconductor die carrier including the steps of forming a plurality of conductive leads, forming a substrate for holding a semiconductor die, the substrate having a plurality of insulative side walls defining an exterior surface of said substrate, each of the side walls having a plurality of lead passages formed therethrough, and simultaneously inserting at least one of the conductive leads into the lead passage of one of the side walls for retention therein and at least one other of the conductive leads into the lead passage of another of the side walls for retention therein.

Abstract: A semiconductor die carrier may include an insulative substrate; an array of groups of multiple electrically conductive contacts arranged in rows and columns on the insulative substrate, wherein the groups from adjacent rows are staggered as are the groups from adjacent columns, and a portion of each group overlaps into an adjacent row or an adjacent column of the groups of the array; a semiconductor die; and structure for providing electrical connection between the semiconductor die and the conductive contacts. A semiconductor die carrier may also include an insulative substrate; a plurality of leads each having an external portion extending out of the semiconductor die.

Abstract: A semiconductor die package includes a housing and a plurality of leads extending through openings in the housing. The package is designed to be mounted to a printed circuit board in both a horizontal configuration and in an upright configuration. In the horizontal configuration, the face of the die is held parallel to the surface of the printed circuit board. An edge of the die faces the printed circuit board when the package is mounted in an upright configuration. The leads are L-shaped so that either an end surface or an outer side surface of the lead can be surface mounted to the printed circuit board. The leads may extend from only one side wall of the housing. In this case, the housing may include a standoff on a bottom surface adjacent a side wall opposite the leads to balance the housing. Alternatively, stabilizing leads may be provided from the opposite side wall to improve horizontal mounting stability.
