Description

A kind of mainboard that is used for Supersmall desk computer

Technical field

The present invention relates to computer technology, particularly relate to a kind of mainboard technology of Supersmall desk computer.

Background technology

The conventional desktop computer volume is big, heavy, it is big to take up space, put also inconvenient (table need be fixed with a mainframe down), and the big machine topology layout is unreasonable, material, space waste greatly, rate of heat dissipation is low.Along with computing machine is commercial as a kind of consumer white, household electrical appliance obtain universal day by day, objective development makes people more and more higher to the requirement of its outward appearance, volume, requires it more attractive in appearance, lighter and handier, requires to update, make its volume littler, more convenient to use, put and move; By slim, light and handy the LCDs big and heavy vacuum crt display unit of substituted volume gradually, by contrast, bulky main frame just more has the necessity that further reduces at the display of present computing machine; And the volume that will dwindle main frame at first will dwindle the area of computer motherboard, though now some has dwindled the compact main frame of computer motherboard, its volume is still inadequately little, can not be supporting and make people satisfied with light and handy LCDs; Some compact computer CPU is to dismantle in addition, and the upgrading of PC is caused significant limitation, has influenced popularizing of these compact computing machines; Also the computer motherboard of some compact computing machine can not use memory bar, hard disk and the CD-ROM drive of desk-top computer, can only use memory bar, hard disk and the CD-ROM drive of notebook, thereby increase cost, makes product be difficult for popularizing.

In this manual, establishing cabinet volume (or volume) is Supersmall desk computer less than the desk-top computer of four cubic decimeters (or rise).

Summary of the invention

At the defective that exists in the above-mentioned prior art, technical matters to be solved by this invention provides a kind of integrated level height, area is little, energy is compatible, components and parts are rationally distributed, eliminate electromagnetic interference (EMI), the mainboard that is used for Supersmall desk computer of the high and low cost of radiating efficiency.

In order to solve the problems of the technologies described above, a kind of mainboard that is used for Supersmall desk computer provided by the present invention, be included in a north bridge chips that is provided with on the mainboard, one South Bridge chip, the integrated chip of various function cards, one CPU, the ide interface socket, one 20 pin power interface sockets, the integrated circuit (IC) chip that other is relevant, at least two USB interface and various Peripheral Interface, the CPU socket of one Socket series, desktop computer is with 184 pin DIMM memory bar slots, and mainboard is the integrated circuit plate structure of at least six layers the two-sided paster of multilayer, is provided for the universal cpu radiating subassembly of MATX/ATX specification mainboard on the mainboard.

Described memory bar slot is a fore-and-aft direction, is arranged on the right-hand member of computer motherboard.

The middle part of described mainboard is provided with CPU, and the front portion of mainboard is provided with south, north bridge chips, and CPU is 74 ± 5mm apart from the distance of south, north bridge chips, and north bridge chips is on the right side, and South Bridge chip is on a left side, between south, the north bridge chips at a distance of 50 ± 4mm.

Described mainboard specification is 170 ± 10mm * 176 ± 10mm.

Described mainboard is provided with a PCI slot.

Described ide interface socket comprises 3.5 inch hard disks of desktop computer and 40 pin ide interface sockets and 2.5 inch hard disks of notebook and the 44 pin ide interface sockets that CD-ROM drive is used that CD-ROM drive is used.

The integrated chip of described various function cards comprises sound card integrated chip, network interface card integrated chip and video card integrated chip.

Described various Peripheral Interface comprises Peripheral Interfaces such as VGA video interface, RJ-45 interface, Line in/out interface, MIC interface.

Utilize the mainboard that is used for Supersmall desk computer provided by the invention,, dwindle the mainboard area, improve the integrated level of mainboard because described mainboard adopts the integrated circuit plate structure of at least six layers the two-sided paster of multilayer; Because described mainboard is the position of layout main chip group scientificlly and effectively, eliminate electromagnetic interference (EMI), make the mainboard that dwindles area, also can work reliably as the mainboard of former MATX, ATX series; Because described mainboard still adopts the CPU socket of Socket series in the mainboard of former MATX, ATX series, relevant wire structures, also can be compatible and expand though make that mainboard of the present invention is little; Because described mainboard still adopts CPU radiating subassembly general in the mainboard of former MATX, ATX series, has improved radiating efficiency, has made things convenient for the dismounting of compatible CPU; Because described mainboard still adopts 184 pin DIMM memory bar slots and 40 pin ide interface sockets in the mainboard of former MATX, ATX series, thereby can use memory bar, the 3.5 inch hard disk or the CD-ROM drives of desktop computer, reduce the complete machine cost of superminicomputer; Put owing to optimized the position of heating components and parts such as CPU, north bridge chips, memory bar on the mainboard and fan, the radiating efficiency of raising computing machine also can be worked the superminicomputer that mainboard of the present invention is installed long-term and stably; After tested: described superminicomputer can stable operation in 50 ℃ environment 3DMAX software at least 8 hours.
