Abstract
A circuit board includes two first insertion holes, a second insertion hole located on one side of the two first insertion holes, a third insertion hole located on the other side of the two first insertion holes, and a number of grounding points. The grounding points are distributed on a periphery of the first insertion holes. The grounding points, the second insertion hole and the third insertion hole together form a shielding layer surrounding the periphery of the first insertion holes. The present disclosure also relates to a backplane connector assembly having a backplane connector and the circuit board. Compared with the prior art, the circuit board disclosed in the present disclosure improves the shielding effect of differential signal terminals, reduces crosstalk and improves the quality of signal transmission.
