    摘要： A printed circuit board (PCB) includes at least one signal layer, a ground layer, at least two signal lines, and at least one grounded line. The signal lines are arranged on the signal layer for transmitting signals. The grounded line is arranged on the signal layer and between the signal lines. A plurality of vias are defined in the grounded line, and the vias are connected to the ground layer. A distance between each two adjacent vias is so arranged that a resonant frequency of an electromagnetic wave transmitted on the grounded line must greater than a highest frequency of the signals transmitted on the signal lines. A related method for designing the PCB is also provided.

    摘要： A signal transmission structure includes a driving circuit block, a receiving circuit block, a main transmission line, and a radial patch. The main transmission line connects the driving circuit block to the receiving circuit block. The radial patch is formed between the driving circuit block and the main transmission line. The radial patch can reduce a switching rate when the signal state of the driving circuit changes rapidly. The radial patch serves as a compensation capacitor, to reduce a rate of switching of signals, and to reduce or even eliminate the problems of crosstalk and overshooting and undershooting of signals. It is of advantage that the radial patch is simple to manufacture and very suitable for mass production.

    摘要： A multilayer printed circuit board (PCB) includes a plurality of signal planes, two reference planes, a signal via, and a stitching via. The signal via passes through all planes for a signal trace flowing therethrough. The stitching via is defined near the signal via and electrically connects to one of the reference plane. The stitching via serves as a stitching capacitor, to reduce the area of the signal current flows in the PCB, even to control crosstalk and lower the noise on the PCB. It is of advantage that the stitching via is simple to manufacture and very suitable for mass production.
