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： 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： An exemplary FPCB includes a signal layer having a differential pair consisting of two transmission lines arranged therein, a ground layer, and a dielectric layer lying between the signal layer and the ground layer. Two sheets made of conductive materials are respectively arranged at opposite sides of the differential pair, and both connected to ground. The sheets are apart from and parallel to the transmission lines. The ground layer has a void defined therein, and the void is located under the two transmission lines.

摘要： An enclosure includes a plate. The plate defines a number of through holes. A hollow shield extends from the edges bounding each through hole. A top side of the shield opposite to the plate is smaller than a bottom side of the shield which is connected to the edges of the through hole. The enclosure can better shield electromagnetic interference (EMI) from the electronic device.
