    • A printed circuit board includes a number of signal layers, a number of ground layers, a first transmission line, a second transmission line, a first via, and a second via. The first transmission is located on one of the number of signal layers. The second transmission line is located on another of the number of signal layers. The first and second vias pass through the printed circuit board. The first via is electrically coupled to the first and second transmission lines, and is isolated from the number of ground layers. The second via is electrically coupled to one or more of the number of ground layers, and is isolated from the other of the number of ground layers to increase an inductance, thus compensating capacitive nature of an open stub and improving signal integrity.
    • 印刷电路板包括多个信号层,多个接地层,第一传输线,第二传输线,第一通孔和第二通孔。 第一个传输位于多个信号层之一上。 第二传输线位于多个信号层的另一个上。 第一和第二通孔穿过印刷电路板。 第一通孔电耦合到第一和第二传输线,并且与接地层的数量隔离。 第二通孔电耦合到多个接地层中的一个或多个,并与多个接地层中的另一个隔离,以增加电感,从而补偿开路短路的电容特性并提高信号完整性。

    • A computing device and a method selects a signal transmission line from a circuit board, computes an actual length of each line segment of the selected signal transmission line, and computes an actual distance between each line segment of the selected signal transmission line and a corresponding line segment of each neighboring signal transmission line. If each actual length is less than or equal to a corresponding reference length and each actual distance is more than or equal to a corresponding reference distance, the device and method determines a design of the selected signal transmission line satisfies the design standards. Otherwise, if any actual length is more than a corresponding reference length, or if any actual distance is less than a corresponding reference distance, the device and method determines the design of the signal transmission line does not satisfy the design standards.

    • A system for operating a differential probe which includes a first metal extension and a second metal extension having the same structures is disclosed. Each of the metal extensions includes a rotatable arm, a rotatable base, and a contact end. The rotatable base and contact end of each of the metal extensions extend from two ends of the corresponding rotatable arm at an angle, the contact ends and the rotatable bases of the metal extensions are parallel to each other. The system controls a mechanical arm to adjust a horizontal distance between the contact ends to be equal to a required horizontal distance by rotating the first metal extension around the rotatable base of the second metal extension clockwise by a rotated angle, and rotating the second metal extension around the rotatable base of the first metal extension counterclockwise by the rotated angle.
