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： 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.
