Patent ID: 6844620

Claim:
A power layout structure of a main bridge chip on a motherboard, used to place the main bridge chip on the motherboard to support its operation, the power layout structure of the main bridge chip comprising: a first signal layer, located on a top layer of the power layout structure of the main bridge chip, the first signal layer at least comprising a power layout layer; a second signal layer, located on a bottom layer of the power layout structure of the main bridge chip, the second signal layer at least comprising a power layout layer, wherein the power layout layer comprised in the first signal layer is symmetrical to the power layout layer comprised in the second signal layer; a first reference voltage layer, located below the first signal layer, used to couple to a reference voltage source, wherein the first signal layer is coupled to the first reference voltage layer; and a second reference voltage layer, located above the second signal layer, used to couple to the reference voltage source, wherein the second signal layer is coupled to the second reference voltage layer.
