The utility model provides a circuit
board structure, and relates to the technical field of circuit boards. The structure comprises a circuit board body, at least two resistance-
capacitance devices and at least four
signal wires, the circuit board body is provided with at least two
signal holes, at least two
backflow ground holes and at least two bonding pad assemblies, each bonding pad
assembly comprises at least two bonding pads which are arranged in sequence, the same resistance-
capacitance device is correspondingly connected with two adjacent bonding pads in the same bonding pad
assembly, the
signal wire is correspondingly connected with the bonding pads connected with the resistance-
capacitance device, and the signal wire is connected with the signal wire. The through bonding pad
assembly and the signal hole are both located between the at least two
backflow ground holes. The quality and stability of signal transmission can be enhanced through the signal hole, the
backflow ground hole provides a plurality of backflow paths, in high-speed signal transmission and high-frequency application,
signal delay and
distortion are reduced, the
signal quality is improved, the device is suitable for high-speed signal transmission, such as 32Gbps, and the bonding pad assembly, the signal hole and the backflow ground hole are compact in
layout structure, small in occupied space and high in reliability. And the high-density arrangement requirement is met.
