Abstract:
The adapter couples a power module to a circuit board. An adapter embodying the present invention can be configured to allow the connection of any power module regardless of pin out to any circuit board. Signal modifying circuitry can also be added to the adapter to enhance or simply modify the signal to the end user's circuit board. The modifying circuitry can act on either the input to the adapter or the output from the adapter. At least one conductive path couples the input interconnects and the output interconnects.
Abstract:
A semiconductor assembly includes a module holder and a semiconductor module, which has a board substrate with conductor tracks and one or more unpackaged semiconductor chips mounted on the substrate, which are connected to conductor tracks on the substrate by electrical contacts. The substrate has at one edge at least one contact strip with connection contact areas, which are connected to at least some of the conductor tracks. The module holder has a plug-in connection for the electrical connection to other components, at least one mating contact strip for the connection to the contact strip of the at least one semiconductor module and electrical conductors between the contact areas of the at least one semiconductor module and electrical contacts of the plug-in connection. The configuration allows semiconductor modules to be connected to the outside world in an economical way.
Abstract:
The present invention features an ultra high density, three-dimensional electronic circuit package suitable for constructing high capacity, high speed computer memory cards and the like. A demountable contact system allows easy test and/or burn-in. A memory card has a number of electrical receptacles adapted to receive a daughter card. The daughter card has memory devices attached to it and a corresponding number of electrical connectors placed along at least one edge, adapted to detachably mate with the electrical receptacles of the memory card. The demountable connectors allow easy rework of the module before optional, permanent solder attach. Bare dies or thin packages are mounted onto daughter cards, which in turn are mounted onto either a motherboard or memory card using pin/hole technology.
Abstract:
A multichip module is provided. The multichip module comprises a rigid substrate including a core material and having an opening, a thin film fixed on an upper surface of the rigid substrate so as to be electrically connected to the rigid substrate and to close the opening, a first chip mounted on the upper surface of the thin film, and a second chip mounted on the under surface of the thin film so as to be located in the opening of the rigid substrate. The rigid substrate and the thin film form a wiring substrate having a composite structure.
Abstract:
A device is provided for structurally and electrically interfacing an integrated circuit (IC) chip with a printed circuit board (PCB) designed for another IC chip, where the two IC chips have different structural and/or electrical operating characteristics. The device provides structural and/or electrical interfaces for interfacing the IC chip with the PCB.
Abstract:
A system for delivering power to a processor enables a DC-to-DC converter substrate to be secured to the processor carrier in the Z-axis direction. The ability to assemble the converter to the processor in this way facilitates assembly compared to systems in which the converter is plugged in to the processor carrier in the direction substantially parallel to the surface of the motherboard.
Abstract:
This discloses a memory module adapter card that allows newer dual in-line memory modules (DIMMs) to be used by computer system boards that were built to use older single inline memory modules (SIMMs) thereby permitting computer owners to update and upgrade older machines without modifying or changing their system boards. This memory module adapter card is designed to connect a memory DIMM inserted into a DIMM socket, carried thereon, to a pair of smaller SIMM sockets on a computer system board such that the DIMM appears to the computer as a pair of the smaller SIMMs that the board was originally designed for. This decreases the need for manufacturing and maintaining an inventory of the older SIMMs and provides owners of older computers the means to extend the useful life of their existing computer system even if the SIMMs designed for the computer no longer exist or are prohibitively expensive or very difficult to locate.
Abstract:
A thin and small computer system that can be used generally for control of equipment or the like, includes a CPU chip, peripheral control chips, and other components mounted in the form of a bare chip, whereby a computer system having a so-called hierarchy architecture can be incorporated in an IC card-like casing. Computer system components are affixedly attached to a double-sided printed wiring board. Electronic components may be attached to the printed wiring board in a bare form and then at least partially sealed with a resin. A system may further include a second printed board which is independent from the first printed board and adhesively attached to a inner surface of the casing and connected to the first printed board by a flexible member. In addition the second circuit board may include structure which enables it to connect to an apparatus for programming an electronic component attached thereto.
Abstract:
Passive device assembly for accurate ground plane control is disclosed. A passive device assembly includes a device substrate conductively coupled to a ground plane separation control substrate. A passive device disposed on a lower surface of the device substrate is separated from an embedded ground plane mounted on a lower surface of the ground plane separation control substrate by a separation distance. The separation distance is accurately controlled to minimize undesirable interference that may occur to the passive device. The separation distance is provided inside the passive device assembly. Conductive mounting pads are disposed on the lower surface of the ground plane separation control substrate to support accurate alignment of the passive device assembly on a circuit board. By providing sufficient separation distance inside the passive device assembly, the passive device assembly can be precisely mounted onto any circuit board regardless of specific design and layout of the circuit board.
