Computer motherboard backplane is not the beginning of the past, the older motherboard, almost never this design, perhaps in some of the high-end products to be able to see, more likely to be a radiator with a fixed device. However, since entering the LGA775, the motherboard backplane design began to pop up, the end of the reason, a large part of the CPU with the increase in heat, CPU overclocking needs, to enhance the cooling performance, radiators do more and more, Even with pure copper design, which makes the radiator weight has been far overload.
Backplane, also known as anti-deformation backplane, located on the back of the CPU base, bear the responsibility to prevent deformation of the motherboard. Anti-deformation of the backplane on the material, size, thickness are strictly limited, the material mainly metal and plastic two categories. Plastic anti-deformation of the back plate hardness is relatively poor, and metal backplane has a better hardness and toughness, while taking into account the cooling performance, to be significantly better than the plastic material backplane.
