The printed circuit board includes an interconnection substrate on which electronic components are mounted and in which a plurality of signal lines are arranged. The signal lines are electrically coupled to the electronic components.

Abstract:
A flexible circuitry is populated with integrated circuitry (ICs) disposed along one or both of its major sides. Contacts are distributed along the flexible circuitry to provide connection between the module and an application environment. A rigid substrate is configured to provide space on one side where the populated flex is disposed while in some embodiments, heat management or cooling structures are arranged on one side of the module to mitigate thermal accumulation in the module.
Abstract:
Flexible circuitry is populated with integrated circuitry (ICs) disposed along one or both major sides. Contacts distributed along the flexible circuitry provide connection between the module and an application environment. A rigid substrate configured with wings diverging from a central axis to create, preferably, a ‘V’-shaped structure provide supportive structure for the populated flex circuitry that is wrapped about an edge of the substrate.
Abstract:
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.
Abstract:
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.

Abstract:
[PROBLEMS]To provide a multilayer wiring board wherein high density wiring exceeding the application limit of the conventional build up wiring boards is made possible. [MEANS FOR SOLVING PROBLEMS]A wiring board is provided with a board, which is formed by stacking along a board flat plane direction of a plurality of dielectric layers arranged along a facing direction of the both main surfaces of the board, and an inner conductor pattern arranged on the surface of the dielectric layer. The adjacent dielectric layers are formed so as to interconnect by being continuously and integrally coupled with each other through being connected at the layer edges on one of the board main planes. The connecting portions of the adjacent dielectric layers are alternately provided on one of the board main planes, and the dielectric layers are formed in a shape of one dielectric sheet that is arranged by being bent.
