摘要： A printed circuit board includes a signal layer and a reference layer. The signal layer is covered with copper foil. A circuit topology for multiple loads is set on the signal layer. The circuit topology includes a driving terminal, a first signal receiving terminal, and a second signal receiving terminal. The driving terminal is connected to a node through a first transmission line. The node is connected to the first and second signal receiving terminals respectively through a second and a third transmission lines. A difference between lengths of the second and third transmission lines is greater than a product of a transmission speed and a rise time of signals from the driving terminal. The reference layer is covered with copper foil, and arranged under the signal layer. A region without copper foil is formed on the reference layer, under the second transmission line.
