    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.

    摘要: A method for controlling impedance of a multi-layer PCB includes establishing a geometric model using simulation software according to a structure of the multi-layer PCB. A first variable (S) and a second variable (W) are respectively defined in the simulation software. The variable S is set equal to a first desired value. An impedance (R) of the transmission line is set equal to a second desired value. The variable W is set to a value according to a relationship between R, S, and W.

    摘要: A printed circuit board includes a signal layer, an insulation layer, and a reference layer. A transmission line is located on the signal layer. A probing pad is located on the transmission line. Two aligned slots defined in opposite sides of the reference layer leaving a connecting portion. The slots and the connecting portion are in vertical alignment with the probing pad. The signal layer, the insulation layer, and the reference layer are configured in a cascading order. An arrangement of the signal layer in relation to the reference layer including the slots and the connecting portion reduces a capacitance effect caused by the probing pad.
