摘要:
A computer system architecture in which functionally compatible electronic components are located on modular printed circuit boards. Thus, a type of processor used by the system can be changed by replacing the printed circuit board incorporating the processor. Similarly a type of peripheral bus used can be changed simply by replacing the printed circuit board containing the peripheral controller. High-density connectors connect the circuit boards. Some embodiments of the invention use a single backplane. Other embodiments place peripheral slots on a second, passive backplane.

A cooling system for a semiconductor die carrier is disclosed that includes a cooling fan disposed at a substantial distance from a semiconductor die carrier, a cooling duct including an inlet portion and an outlet portion, and a heat exchanger disposed on an upper surface of the semiconductor die carrier. The cooling duct inlet portion is attached to the cooling fan and the cooling duct outlet portion is disposed in close proximity to the heat exchanger. The cooling fan draws ambient air into the cooling duct and the ambient air exits the cooling duct outlet portion and passes in a heat exchange relationship with the heat exchanger.

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.

A computer system includes an exterior casing having an opening therein to permit user access to peripheral devices, such as floppy drives, CD ROM drives, tape drives, or optical drives. A door driven by a reversible motor slides along the exterior casing to open and close the opening in the exterior casing. A user may activate a sensor provided on the exterior casing to selectively open or close the door. The sensor may be a light-sensitive sensor, a voice-activated sensor, or a proximity sensor. Alternatively or in addition, the user may open and close the door via a system processor, for example, by entering commands via a keyboard. The door may slide along tracks within the exterior casing. In addition, the door may be locked in a closed position and unlocked to allow opening.

A male connector connects with a female connector to establish an electrical connection. The male and female connectors each include a connector housing having hold-down tabs at opposite ends thereof for securing the connector housing to a substrate. The hold-down tabs are staggered or diagonally located such that one hold-down tab is proximal a first side of the connector housing and the other hold-down is proximal a second side of the connector housing. The staggered or diagonally-located hold-down tabs stabilize the connector housing against rocking or other movement on the substrate. The arrangement of hold-down tabs also permits the connector housing to nest or merge with another similarly-designed connector housing. The nested or merged connector housing conserve substrate space and permit a higher density of contacts in a given space on the substrate, whether the space is at an edge or in an interior of the substrate. The male and female connector housings include side walls having complementary polarization features. The polarization features on the female connector housing may be formed on a detachable polarization cap. A side of the male connector housing includes a stop member for providing a positive stop for the female connector and to prevent rocking. The stop member is configured to permit side-to-side nesting of male connector housings.

Disclosed is a decorative panel for attachment to the exterior of a computer enclosure including a fastener receiving portion for facilitating attachment of the decorative panel to an outer surface of the computer enclosure, a plurality of irregular geometric shaped surface depressions on a first surface of the decorative panel fixed in an ornamental arrangement, and at least one bore which extends completely through the decorative panel adapted to allow air to flow through the decorative panel and into an interior of the computer enclosure.
摘要:
A computer system includes a computer cabinet, a plurality of printed circuit boards housed within the computer cabinet, a processor secured to at least one of the printed circuit boards, a power supply cabinet remote from the computer cabinet, a power supply housed within the power supply cabinet and a signal interconnect unit, coupled to the computer cabinet and the power supply cabinet, for providing an electrical path between the computer cabinet and the power supply cabinet. The printed circuit boards and the slots into which they are inserted have corresponding color code labels. The purpose of this is to clearly identify the location of the slot which corresponds to the printed circuit board of the same color.
