Embodiments of the present application provide a printed circuit board and a communication device, which relate to the technical field of circuit boards and are used to solve the problem of serious signal crosstalk between two adjacent pairs of signal crimping holes. The printed circuit board includes a connector insertion area, a plurality of rows of crimping holes are arranged in the connector insertion area, each row of crimping holes includes at least two pairs of signal crimping holes, and each pair of signal crimping holes includes two signal crimping holes contact holes; along the row arrangement direction of the crimping holes, at least one grounding crimping hole is provided on both sides of each pair of signal crimping holes, and the depth of the grounding crimping holes is greater than or equal to the depth of the signal crimping holes. The crimping hole includes a main hole and a shielding member located on at least one side of the main hole, and part of the sidewall of the main hole is a part of the sidewall of the shielding member; the sum of the lengths of the main hole and the shielding member in the first direction is greater than the signal crimping The length of the hole in the first direction. The communication device includes the above-mentioned printed circuit board and a connector mating therewith. |
