The development of the motherboard there since the time of IBM PC Design in 2524 by developing the size, shape of เมนบอร์ survived used with PC version And it shall come to pass, also develop the use with generation x T
.Times to generation at. Right to create a standard size of the motherboard. The machine developed to use the size of the motherboard at essentially
.Until, when the development of advanced technology a lot. What to consider more important on the motherboard, until about the year 1997.2538 or while the PC has come to the Pentium. บริษัทอินเทล proposed the size of standard motherboard and called ATX which used together to this day
.From the size of the ATX has continued to do the development machine is compact. By reducing the size of the motherboard down and called microATX and reduced again in a name FlexATX
major characteristics of ATX เมนบอร์ D ATX size 12 inches. X 9.6 inches is the standard size that can take on change. And so the motherboard take change. Design of the motherboard, thus must consider the size and position of the screw hole pedestal. And put it in the machine (box).
.The size of the ATX is designed to have the proper size to put the important and essential for the CPU, the Croton system expansion, arrangement of equipment must be perfect and simple position in the cable. Are connected on the board!The agility of putting the device into the slots. Put CPU fan and channel port extension is พอร์ตท needed with extended, such as serial port. Standard parallel port port port port various USB TV in / out
.The design must consider the channel the flow of air to heat and reduce noise occurred, especially when the input device. , on the board, such as fan
.On the board take welding secondary to power supply party, which at present uses the standard - 5 volt - 12 volt and 3.3 v. the distance must be reasonable to assemble easily.
board motherboard microATX is scaled down in size is only 9.6 inches multiplied 9.6 ". The purpose is to make the packing box is smaller. But from the smaller areas in the need to reduce the number of slots of various makes machine main board, a microATX has the capability to expand the System Co., Ltd. And in BC.2542 in เทอล has developed a new version of the motherboard with a small down again by the name model FlexATX with main board size only 9 inches multiplied 7.5 inches. To make the size PC is small.
