Embodiment Construction

[0011] Such as Figure 1-3 As shown, it is a preferred embodiment of the printed circuit board 10 of the present invention. The printed circuit board 10 includes a first mounting area 11 for mounting a first type chip 20 and a mounting area 11 for mounting a second type chip 30. The second installation area 12 . In this embodiment, the first type chip 20 is a 64pin input / output (I / 0) control chip, and the second type chip 30 is a 128pin input / output (I / 0) control chip.

[0012] The periphery of the first mounting area 11 is provided with some pads 110 for connecting the 64pin I / 0 control chip 20, and the periphery of the second mounting area 12 is provided with some pads for connecting the 128pin I / 0 control chip 30 120. In this embodiment, the first installation area 11 is disposed in the second installation area 12 , and the 64pin I / 0 control chip 20 and the 128pin I / 0 control chip 30 have several pins with the same definition.

[0013] In this embodiment, the user can ch...

Abstract

A printed circuit board includes a first installation area where a first type of chip is installed and a second installation area where a second type of chip is installed. The periphery of the first installation area is provided with a plurality of bonding pads for connecting the first type of chip. The periphery of the second installation area is provided with a plurality of bonding pads for connecting the second type of chip. The first type of chip and the second type of chip have a plurality of pins with the same definition. In the second installation area and the first installation area, the bonding pads corresponding to the pins, having the same definition, of the two chips are electrically connected. The printed circuit board of the invention can be connected to in-out control chips with different models according to user demands. Thus the production cost of manufacturers is reduced, and the multi-functionalization of the printed circuit board is realized.

Description

technical field [0001] The invention relates to a printed circuit board. Background technique [0002] Nowadays, an I / O control chip with a serial interface and a parallel interface is usually arranged on a computer motherboard to connect peripheral devices such as a mouse, a keyboard, and a printer. However, due to different customer needs, different customers have different requirements for the number of serial interfaces and parallel interfaces on the main board, so that manufacturers need to produce different numbers of serial interfaces or parallel interfaces or serial and parallel interfaces coexisting according to customer needs. circuit board. This increases the production cost and time of the manufacturer, and greatly reduces the production efficiency. Contents of the invention [0003] In view of the above, it is necessary to provide a printed circuit board on which two types of input and output control chips are disposed at the same time, so as to meet the dif...
