摘要： A PCB includes a number of insulation layers, a number of circuit layers, a signal-interfering component, and a signal-sensitive component. The circuit layers and the insulation layers are stacked alternately. The circuit layers include at least two first circuit layers, a second circuit layer, and a ground layer. The ground layer has a first side and a second side facing away the first side. The first circuit layers are positioned near the first side and include an outmost first circuit layer and at least one inner first circuit layer positioned between the outmost first circuit layer and the ground layer. The second circuit layer is positioned near the second side. The signal-interfering component is positioned on the outmost first circuit layer. The signal-sensitive component is positioned on the second circuit layer. Each inner first circuit layer defines a copper-remove area corresponding to an orthogonal projection of the signal-interfering component thereon.
