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:
The invention relates to arrangements for the power supply of integrated circuits. Various solutions are proposed with a view to guaranteeing a power supply satisfying all the technical requirements with regard to ever greater permissible load jumps, greater permissible current change rates and ever tighter tolerances regarding the constancy of the supply voltage in question. In particular an arrangement with an integrated circuit (2) mounted on a bearing means (1) and a power supply module arrangement (3) is proposed, which is placed on the combination of bearing means (1) and integrated circuit (2) and whose base extends at least partially over the base of the integrated circuit (2) and/or all around the base of the integrated circuit (2).
Abstract:
A component mounting method of a multilayer printed wiring board includes a plurality of solder bumps to mount electronic components formed on both of or either of the front and back thereof, wherein when the solder bumps are formed of any of first, second, third and fourth solders, the first, second, third and fourth solders have different melting points and the melting points of the first, second, third and fourth solders are arranged as the melting point of the first solder, the melting point of the second solder, the melting point of the third solder and the melting point of the fourth solder in order of high melting point and the first, second, third and fourth solders are sequentially used to solder electronic components and the like in order of high melting point. Further, in that case, it is preferable that the solder bump having large volume should be soldered earlier than other solder bumps. This multilayer printed wiring board is easy to mount components, excellent in work efficiency or easy in reworkable process and a mounting method of such multilayer printed wiring board is also provided.
Abstract:
[Object] To provide a component-containing module capable of reducing cost and improving yield. [Solving Means] A component-containing module A includes a module substrate 1 having first wiring lines 2 formed on the top surface of the module substrate; a first circuit component 7 mounted on the first wiring lines of the module substrate; a submodule substrate 10 having an area smaller than the area of the module substrate and mounted on the first wiring lines of the module substrate at a position where the first circuit component is not mounted; a second circuit component 15 mounted on second wiring lines 11 formed on the top surface of the submodule substrate; and an insulating resin layer 20 formed on the entire top surface of the module substrate so as to encompass the first circuit component, the second circuit component, and the submodule substrate. Application of a substrate having a wiring accuracy higher than that of the module substrate 1 to the submodule substrate 10 allows an integrated-circuit element 15a to be mounted on the submodule substrate, and realizes a highly reliable and low-cost component-containing module.
Abstract:
A system for providing dual 10 GB uplinks in the front side of a single rack unit switch that stacks two MSA X2 I/O devices in a limited space. In one embodiment the two X2 I/O devices are mounted on opposite sides of a single circuit board positioned above the motherboard.
Abstract:
An Advanced Mezzainine Card An Advanced Mezzanine Card (AMC) adapter may be used to connect a non-AMC mezzanine cared to an AMC carrier. The AMC adapter may include a card edge connector configured to be connected to an AMC connector on the AMC carrier and one or more mezzanine connectors configured to be connected to the non-MC mezzanine card. The AMC adapter may also include a bridge to convert between communication protocols used by the non-AMC mezzanine card and the AMC carrier. Of course, many alternatives, variations, and modification are possible without departing from this embodiment.
