    摘要: In a method for verifying a printed circuit board (PCB) layout using a computing device, a PCB simulation file is obtained from a storage device of the computing device, and a PCB image is displayed on a display device according to the PCB simulation file. The PCB image includes multiple signal lines and switching voltage regulator nodes (SVRN). A SVRN to be checked is selected from the PCB image, and all signal lines around the SVRN are searched. The method calculates a layout distance between the selected SVRN and each of the searched signal lines, and generates a graphical window interface to position a signal line whose layout distance is equal to or less than the minimum distance. The method further modifies the layout of the positioned signal line to satisfy a layout design specification by increasing the layout distance to the minimum distance.

    摘要: A signal integrity test system and method uses an oscilloscope to test a signal on each test point of a transmission line, obtains test parameter values of the signal on each test point, and compares the test parameter values with preset standard values. If any test parameter value does not match a corresponding preset standard value, a time-domain reflectometer is used to test an impedance value of the test point. If the impedance value matches a standard impedance value of the transmission line, the system and method determines the signal on the test point satisfies integrity requirements.

    摘要: A clamping apparatus includes a motor, a first cone gear secured to a shaft of the motor, and two clamping bodies attached to opposite sides of the motor. Each of the clamping bodies includes a second cone gear meshing with the first, a threaded post fixed to the second cone gear, a carriage threadedly connected with the threaded post, and a clamp arm fixed to the carriage. The motor rotates the first cone gear, and in turn the second cone gears and the corresponding threaded posts. With the rotation of the threaded posts, the carriages move towards or away from each other, whereby the clamp arms cooperatively acquire an object between the clamp arms, or release the object therefrom.

    摘要: A printed circuit board includes a signal plane and a reference plane. The signal plane includes a pad, a passive element mounted on the pad, and a signal transmission line electrically connected to the passive element via the pad. The reference plane provides a return path for a signal transmitted through the passive element and the signal transmission line. A void is defined in the reference plane corresponding to the passive element, to increase a length of the return path. A length of a first axis, perpendicular to the signal transmission line, of the void satisfies a following equation: W 1 ≈ 8 ⁢ Wpad + 10 ⁢ T 0.8 ⁢ Wtrace + T , wherein Wpad is a width of the pad, Wtrace is a width of the transmission line, T is the height of the pad.
