Description

Option board {A OPTION BOARD}

The present invention relates to an option board, and more particularly to an option board that is easy to upgrade.

In a computer, a number of boards are installed in an organic relationship with each other. The main board, which we commonly refer to, is the most important of the various boards, and is equipped with a central processing unit (CPU) that is responsible for the control and operation of all programs executed in the computer device. In addition, an option board is additionally mounted on the main board to improve the function of the computer device.

It is true that graphics performance is changing rapidly and frequently, as is the performance improvement across computer systems. Usually, a graphics chip company develops and announces two to six new chipsets a year, which means that new graphics boards are released almost every 1.5 months.

Computer systems companies are working closely with 1-5 graphics chipsets, so if two graphics chipsets are announced each new chipset company wants to develop chip modes for five graphics chipsets, at least 10 boards a year You need to create a new one. In particular, applying it to volume production requires ten new system models to be created or upgraded.

Figure 1 shows a typical graphics board.

The general graphics board 100 includes a graphics chipset 104, a ROM 106, an RGB stage (not shown), a CLK stage (not shown), and a memory 108 stage on one circuit board 102. have.

For example, in the graphic board 100, the type / capacity of the graphic chipset 104 or the memory is mainly upgraded.

As such, graphic boards that are upgraded according to chipset or memory changes have a problem of reworking ARTWORK from the beginning to create a new circuit board. On the other hand, the part where the graphics chipset and the memory are mounted requires a multi-layer circuit board having 4 layers or 6 layers or more, and the rest part may be a 2 layer circuit board structure. The manufacturing cost is inevitably produced in a multilayer structure.

As described above, the conventional graphics board has a problem in that the cost of the change and the time required for the change are long because the entire circuit board needs to be changed and replaced when the graphic chipset or the memory is upgraded.

The present invention is to solve such a conventional problem, an object of the present invention is to provide an option board of a new type that can be easily upgraded and can reduce the cost during the upgrade.

According to a feature of the present invention for achieving the above object, an option board connected to the expansion socket of the main board to add and expand the function to the computer is a connector that is mounted with a plurality of semiconductor integrated circuit devices and connected to the expansion socket A first circuit board having a; A socket installed on the first circuit board; A second circuit board having a connector mating with the socket and having a chipset and a memory mounted on one surface thereof.

In this option board, the second circuit board may have a multilayer structure, and the first circuit board may have a two-layer structure. This option board may be a graphics board.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to FIGS. 2 and 3. In the drawings, components that perform the same function are denoted by the same reference numerals.

These graphics boards include other types of modem cards, moving picture experts group (MPEG) boards, video boards, sound cards, etc., which are additionally attached to the main board to enhance the functions of computer devices. It can also be understood as an optional board.

3 is a view illustrating a state in which a second circuit board is coupled to a first circuit board in the graphic board of the present invention.

2 and 3, a graphic board 10 according to an embodiment of the present invention is divided into a first circuit board 12 and a second circuit board 14. The first circuit board 14 includes a semiconductor integrated circuit device such as a ROM 24, an RGB terminal (not shown), and a CLK terminal (not shown) except for a graphics chipset and a memory. The first circuit board 12 is provided with a socket 20. The second circuit board 14 is connected to the socket 20. The second circuit board 14 has a connector 22 having a plurality of pins mating with the socket 20. Meanwhile, a graphics chipset 16 and a memory 18 are mounted on the second circuit board 14 to perform graphics functions in association with semiconductor integrated circuit devices mounted on the first circuit board 12. For example, it is preferable that semiconductor integrated circuit devices such as the graphics chipset 16 and the memory 18 that are mainly changed and upgraded be mounted on the second circuit board 14. For example, the socket and the connector may be composed of a PPGA type socket and a connector mating with the PPGA socket.

Since the memory interface of the second circuit board 14 is connected to the graphics chipset, the total number of connector pins connected to the socket according to the chipset may be constantly taken regardless of the memory type or the capacity.

On the other hand, the first circuit board 12 and the second circuit board 14, the first circuit board 12 in which integrated circuit devices with relatively simple circuits are mounted to efficiently bring the overall cost of manufacturing the board. It is preferable that the second circuit board 14 on which the graphic chipset 16 and the memory 18 mounted on the layered and complicated circuit are mounted in a four-layer or six-layer structure.

The structural feature of the present invention is that the graphic board is divided into a first circuit board and a second circuit board, and the first circuit board and the second circuit board have sockets and connectors for interconnection.

In general, in the graphics board 10, the type or capacity of the graphics chipset 16 or the memory 18 is mainly upgraded. Therefore, in order to upgrade the graphic board 10 of the present invention, instead of changing the entire circuit board as in the prior art, only the second circuit board 14 on which the graphic chipset 16 and the memory 18 are mounted may be replaced. . Therefore, the graphic board 10 of the present invention can be upgraded at a faster and more reasonable price.

For example, since the graphic board 10 of the present invention can be developed, purchased, and sold by dividing into the first circuit board 12 and the second circuit board 14, it can be easily upgraded by the consumer and the cost can be greatly reduced. have.

As described above, the graphic board of the present invention needs to replace only the second circuit board when the graphic chipset or the memory is upgraded, thereby reducing the cost and the time required for the change.

Applying the present invention as described above, it is easy to upgrade and only need to replace the second circuit board has the advantage that can be upgraded at a faster and more reasonable price.
