Abstract

The utility model relates to the field of main board products and particularly relates to a small-size main board comprising a front panel, a back panel, and a rear panel. The rear panel is arranged on one edge of the main board; the length of the rear panel and that of the main board edge where the rear panel is arranged are identical; four I/O (Input/Output)interfaces matched with the edge lengths of the main board are arranged on the four edges of the front panel respectively; an ancillary circuit is arranged in the center of the front panel; and an ancillary chip connected to the ancillary circuit in the front panel, a main I/O chip connected with the I/O interface in the front panel, an internal memory chip and a system level chip are arranged on the back panel. The functions of a traditional CPU, a north bridge, a south bridge, and a display card are integrated on the system level chip to realize main functions. In addition, the back patch welding technique is adopted to arrange both the main chip and the internal memory chip at the back of the main board, so that the volume of the main board is reduced greatly.

Description

A kind of small size mainboard

Technical field

The utility model relates to the mainboard product scope, is specifically related to a kind of small size mainboard.

Background technology

At present, general computer motherboard all is to have functions such as data operation, signal transmission, system management by what CPU, north bridge chips, South Bridge chip and other electric component group became.Now the mainboard minimum dimension of common layout is the 244mm * 244mm of mATX specification specifies on the market, and normally master chip such as CPU, north bridge, south bridge and memory slot etc. all are arranged in the mainboard front, and it is peripheral on one side that the I/O interface only is arranged in mainboard.Concrete mATX structure as shown in Figure 1, cpu12, north bridge 13,15 3 master chips of south bridge are arranged from the upper right corner to the lower left corner successively.Memory slot 16 be positioned at cpu12 under, near the lower edge of plate.I/O interface 14 is positioned at the left side of south bridge.Rear panel 11 is positioned at the upper limb of plate.On common mATX mainboard, because element is more, computer motherboard often has bigger area.

In today of computer technology develop rapidly, various electronic intelligence equipment are just progressively to miniaturization, integrated development, a lot of small intelligent equipment need be in narrow space integrated high-performance computer mainboard as the platform of information processing, these equipment also propose very high requirement because its service condition is relatively harsher to the computing machine volume.Adopt the computer motherboard of common-use size design often to be difficult to these requirements for special equipment.

Summary of the invention

For overcoming above-mentioned defective, the purpose of this utility model promptly is to provide a kind of small size mainboard.

The purpose of this utility model is achieved through the following technical solutions:

A kind of small size mainboard of the utility model comprises: front plate, back panel and rear panel,

Described rear panel is arranged on an edge of this mainboard, and the length of described rear panel equates with the length of side at the mainboard edge at rear panel place;

On the four edges of described front plate, be respectively arranged with four groups of I/O interfaces that are complementary with the mainboard length of side, be provided with auxiliary circuit in described front plate central authorities;

Main I/O chip, memory chip, system level chip that described back panel is provided with the companion chip that is connected with auxiliary circuit in the front plate, is connected with I/O interface in the front plate, integrated CPU, north bridge, south bridge and video card on the described system level chip.

Use on the utility model mainboard traditional C PU, north bridge, south bridge, the integrated system level chip (SoC) of video card function are realized major function, also comprise I/O interface and relevant auxiliary integrated circuit on I/O extended chip, memory chip, panel connector, the plate in addition.Use the SoC chip of high integration can effectively reduce the quantity and the volume of master chip, thereby reduce the overall dimensions of mainboard.And the utility model uses the back of the body to paste solder technology, and master chip and memory chip all are arranged in the mainboard back side, simultaneously the position of I/O interface is expanded to the whole periphery of mainboard.Make the mainboard size narrow down to 156mm * 102mm like this from the mATX specification.

Description of drawings

In order to be easy to explanation, the utility model is done to describe in detail by following preferred embodiment and accompanying drawing.

Fig. 1 is the structural representation of common mATX specification mainboard;

Fig. 2 is the utility model mainboard small size mainboard Facad structure synoptic diagram;

Fig. 3 is the utility model mainboard small size mainboard reverse side structural representation.

Embodiment

In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.

See also Fig. 2 and Fig. 3, a kind of small size mainboard of the utility model comprises: front plate 24, back panel 31 and rear panel 21,

Described rear panel 21 is arranged on an edge of this mainboard, and the length of described rear panel 21 equates with the length of side at the mainboard edge at rear panel 21 places;

On the four edges of described front plate 24, be respectively arranged with four groups of I/O interfaces 22 that are complementary with the mainboard length of side, be provided with auxiliary circuit 23 in described front plate 24 central authorities;

Main I/O chip 33, memory chip 35, system level chip 34 that described back panel 31 is provided with the companion chip 32 that is connected with auxiliary circuit 23 in the front plate 24, is connected with I/O interface 22 in the front plate 24, integrated CPU, north bridge, south bridge and video card on the described system level chip 34.

Front plate has only I/O interface 22 and auxiliary circuit 23 thereof in the utility model, and I/O interface 22 distributes near the periphery on whole whole four limits of plate;

And in back panel 31, Cpu, north bridge, south bridge, video card all are integrated in the SoC chip 34, and memory chip 35 is positioned at SoC chip right side, and main I/O chip 33 is positioned at plate central authorities, and companion chip 32 is positioned at directly over the SoC chip.SoC chip 34 uses the TunnelCreek of Intel Company, and memory chip 35 uses K4T1G164QE, and main I/O chip 33 uses the Topcliff of Intel Company, and I/O interface 22 is positioned at the plate front, comprises LPT, serial ports, VGA, SATA, USB, sound etc.
