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.

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： An enclosure includes a plate. The plate defines a number of through holes. A first shield extends from an edge bounding each through hole. A second shield extends from the edge bounding each through hole, opposite to the first shields. Each through hole is partially covered by a corresponding first shield and a corresponding second shield. The enclosure with the shields can shield the electronic device from electromagnetic interference.

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 signal transmission apparatus includes two circuit layers. First and second ground sheets each has a rectangular area are arranged in the two circuit layers respectively. A third ground sheet is arranged between the two circuit layers. A differential pair includes a transmission line arranged between the first and third ground sheets and a transmission line arranged between the second and third ground sheets. The first to third ground sheets have same electric potential. Projections of the two rectangular areas on a surface where the third ground sheet in only have one common border with the third ground sheet. The third ground sheet is formed by extending the common border along a signal transmission direction. The differential pair includes a number of section pairs each composed of two sections arranged in the two transmission lines symmetrically. Every two adjacent section pairs are equivalent to a capacitor and an inductor.
