A power distribution method and apparatus for a multilayer printed circuit board (PCB), and a PCB. The method comprises: dividing the power input at a power input end of a multilayer PCB into multiple paths of power according to a preset ratio, the preset ratio being used for indicating a power distribution ratio among the multiple paths of power; and transmitting a first type of power in the multiple paths of power on surface layers of the multilayer PCB and transmitting a second type of power in the multiple paths of power on inner layers of the multilayer PCB, the first type of power and the second type of power constituting the multiple paths of power. The problems of high costs, complex design and large occupied area of the PCB in power distribution of a multilayer PCB are solved, power distribution can be performed among different layers of the PCB, costs are saved, and the multilayer board is fully taken advantage of to achieve a more reasonable PCB layout. |
