摘要： A design method of printed circuit boards includes the following steps. First, simulate a printed circuit board including power layers, and vias connected to all the power layers. Then, change connections of the vias that tend to draw too much current to be connected to fewer power layers, than the vias that tend to draw less current. Repeat adjusting connections of the vias until all vias draw a similar amount of current such that no via draws more current than an upper limit the vias are designed for. Finally, according to the results, design/fabricate a PCB with vias respectively insulated, as needed, from the power layers that do not need to be connected to the vias.

摘要： A printed circuit board includes a first layout layer, a second layout layer, a copper foil layer, a first via and a second via. The first layout layer has a first signal line and a second signal line, each of which has a curved first portion. The second layout layer has a third signal line and a fourth signal line, each of which also has a curved first portion. The curved first portions of the first signal line, the second signal line, the third signal line and the fourth signal line are coupled to the first via and the second via. In this case, the curved first portions of the first signal line, the second signal line, the third signal line and the fourth signal line cooperatively generate spiral inductance characteristic.

摘要： In a method for testing serial attached SCSI (SAS) ports of a server using a computing device, the computing device connects to an oscilloscope and a mechanical arm that is equipped with a test fixture having a probe. The mechanical arm controls the probe to be plugged into one of the SAS ports. The method adjusts an intensity grade of the SAS signals through the SAS port, and controls the SAS port to generate a SAS signal corresponding to the intensity grade. The test fixture obtains the SAS signal from the SAS port, and the oscilloscope measures test parameters of the SAS signal. The method analyzes values of the test parameters to find an optimal SAS signal, determines an intensity grade of the optimal SAS signal as a driving parameter of the SAS port, and accordingly generates a test report of the SAS ports.
