摘要
Provided are vertical transitions which have the high electrical performance and the high shielding properties in the wide frequency band in a multilayer PCB, printed circuit boards with the vertical transitions and semiconductor packages with the printed circuit boards and semiconductor chips. In vertical transitions for a multilayer PCB, a wave guiding channel is a conductor which includes at least more than one of signal vias 201, an assembly of ground vias 202 surrounding the signal via, ground plates from conductor layers of the PCB connected to the ground vias, closed ground striplines 205 connecting the ground vias and power supply layer.
