摘要： 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.

摘要： A compensation method compensates for a length offset between a first transmission line and a second transmission line of a differential signal transmission. The compensation method includes calculating a transmission speed of a first signal in the first transmission line, measuring lengths of the first and second transmission lines, calculating a transmission time of the first signal in the first transmission line, and calculating a relationship between permittivity values of the first and second transmission lines. The compensation method further changes the permittivity values of the first and second transmission lines according to the relationship.

摘要： A method of testing a printed circuit board (PCB) acquires test points from a wiring diagram of the PCB. Frequency domain tested items for each test point and a standard value of each frequency domain tested item are preset. A distance between a preset fiducial point and each test point is computed to create a testing order of the test points according to the distances. The frequency domain tested items of each test point are computed according to the testing order. A pass or a failure of each test point is displayed according to a determination of if each of the computed frequency domain tested items within the corresponding standard value, and a test result of the PCB is output according to the passes or the failures.
