A flex circuit is populated on one or both sides with plural integrated circuit die. In a preferred mode, the flex circuit is populated with flip-chip die. One side of the flex circuit has a connective facility implemented in a preferred mode with edge connector contacts. The flex circuit is disposed about a substrate to form a circuit module that may be inserted into an edge connector such as ones typically found on a computer board.

Die module system

Flexible circuitry is populated with integrated circuitry (ICs) disposed along one or both of its major sides. The populated flexible circuitry is disposed proximal to a rigid substrate to place the integrated circuitry on one or both sides of the substrate with one or two layers of integrated circuitry on one or both sides of the substrate. The rigid substrate exhibits adhesion features that allow more advantageous use of thermoplastic adhesives with concomitant rework advantages and while providing flexibility in meeting dimensional specifications such as those promulgated by JEDEC, for example.

Modified core for circuit module system and method

Flexible circuitry is populated with integrated circuitry (ICs), and contacts are distributed along the flexible circuitry to provide connection to an application environment. The flexible circuitry is disposed about a rigid substrate, placing the ICs on one or both sides of the substrate with one or more layers of integrated circuitry on one or both sides of the substrate. The substrate is preferably devised from thermally-conductive materials and one or more thermal spreaders are in thermal contact with at least some of the ICs. Optionally, as an additional thermal management feature, the module may include a high thermal conductivity thermal sink or area that is disposed proximal to higher thermal energy IC devices. In preferred embodiments, extensions from the substrate body or substrate core encourage reduced thermal variations amongst the ICs of the module while providing an enlarged surface for shedding thermal energy from the module.

Circuit module with thermal casing systems

Flexible circuitry is populated with integrated circuitry disposed along one or both of its major sides. Contacts distributed along the flexible circuitry provide connection between the module and an application environment. The circuit-populated flexible circuitry is disposed about an edge of a rigid substrate thus placing the integrated circuitry on one or both sides of the substrate with one or two layers of integrated circuitry on one or both sides of the substrate. The substrate form is preferably devised from thermally conductive materials and includes a high thermal conductivity core or area that is disposed proximal to higher thermal energy devices such as an AMB when the flex circuit is brought about the substrate. Other variations include thermally-conductive clips that grasp respective ICs on opposite sides of the module to further shunt heat from the ICs. Preferred extensions from the substrate body or substrate core encourage reduced thermal variations amongst the integrated circuits of the module.

Heat sink for a high capacity thin module system

Provided circuit modules employ flexible circuitry populated with integrated circuitry (ICs). The flex circuitry is disposed about a rigid substrate. Contacts distributed along the flexible circuitry provide connection between the module and an application environment. A strain relief portion of the flex circuitry has preferably fewer layers than the portion of the flex circuitry along which the integrated circuitry is disposed and may further may exhibit more flexibility than the portion of the flex circuit populated with integrated circuitry. The substrate form is preferably devised from thermally conductive materials.

Flex circuit constructions for high capacity circuit module systems and methods

A flexible circuit is populated on one or both sides and disposed about a substrate to create a circuit module. Along one of its edges, the flex circuit is connected to a connective facility such as a multiple pin connector while the flex circuit is disposed about a thermally-conductive form that provides structure to create a module with plural layers of circuitry in a single module. In preferred embodiments, the form is metallic and, in alternative preferred embodiments, the module circuitry is disposed within a housing. Preferred embodiments may be devised that present a compact flash module within a housing that may be connected to or into a system or product through a connective facility that is preferably a male or female socket connector while the housing is configured to mechanically adapt to an application environment.

Compact module system and method

Multiple DIMM circuits or instantiations are presented in a single module. In some embodiments, memory integrated circuits (preferably CSPs) and accompanying AMBs, or accompanying memory registers, are arranged in two ranks in two fields on each side of a flexible circuit. The flexible circuit has expansion contacts disposed along one side. The flexible circuit is disposed about a supporting substrate or board to place one complete DIMM circuit or instantiation on each side of the constructed module. In alternative but also preferred embodiments, the ICs on the side of the flexible circuit closest to the substrate are disposed, at least partially, in what are, in a preferred embodiment, windows, pockets, or cutaway areas in the substrate. Other embodiments may only populate one side of the flexible circuit or may only remove enough substrate material to reduce but not eliminate the entire substrate contribution to overall profile. The flexible circuit may exhibit one or two more conductive layers, and may have changes in the layered structure of have split layers. Other embodiments may stagger or offset the ICs or include greater numbers of ICs.

High capacity thin module system and method

Memory module flex circuitry is devised to accommodate packaged integrated circuit devices (ICs) of varying heights or thicknesses. The invention may be employed to advantage in a variety of modules that employ flex circuitry including, but not limited to, fully-buffered, registered or more simple memory modules. Many such modules may replace conventionally-constructed DIMMs without change to the system in which the module is employed. Regions of the flex circuitry devised to provide one or more mounting locales for ICs are delineated, in part, from the main body of the flex circuit. The delineation may be implemented in a preferred embodiment by separating a designated IC mounting area or peninsula from the main body of the flex circuitry either with isolating areas or separations or with tabs that extend from the primary perimeter of the flex circuitry.

Memory module system and method

A circuit module shunts thermal energy into a chassis component or a part of the box of the computing application in which the module is employed. In one preferred mode, a flex circuit is populated along each of its first and second major sides with two ranks of ICs which are, preferably, array type (CSP) devices. Insertion contacts are disposed in two sets on the first side of the flex circuit typically between the two ranks of ICs along the first side of the IC. A substrate with first and second lateral sides provides a form for the module. That substrate is preferably comprised of metallic material and exhibits an edge about which the flex circuit is wrapped and an extension at the other extremity of the substrate that is thermally connected to a chassis component of the application, either directly or, preferably, through a thermal conduit such as a thermally conductive compliant material.

Module thermal management system and method

A flexible circuit has contacts for mounting in a socket or card edge connector. The flexible circuit includes integrated circuit devices mounted on both sides of the edge connector contacts. Preferably, the flexible circuit is wrapped about an edge of a rigid substrate and presents contacts on both sides of the substrate for mounting in a socket. Multiple flexible circuits may be overlaid with the same strategy. The flexible circuit may exhibit one or two or more conductive layers, and may have changes in the layered structure or have split layers.
