The utility model provides a circuit
board structure and a socket structure, the circuit
board structure comprises a circuit board, the circuit board is provided with a first surface, the first surface is provided with at least one first bonding pad, and when there are a plurality of first bonding pads, the first bonding pads are arranged at intervals according to a preset state; the circuit board is provided with via holes in the centers of the first bonding pads so as to form annular bonding pads at the first bonding pads, and the via holes are in one-to-one correspondence with the first bonding pads; the
radius of the annular bonding pad is larger than 0.3 mm, and the annular bonding pad can be used for being connected with the
welding face of the male socket and the
welding face of the female socket in an attached mode. The
radius of the annular bonding pad is larger than 0.3 mm, and the area of the bonding pad is increased, so that when the male socket and the female socket are welded to a circuit board, the use amount of
soldering paste can be increased, it can be guaranteed that sufficient
soldering paste exists between the
welding face and the annular bonding pad, the attachment face of the
soldering paste is increased, and the welding quality of the male socket and the female socket is improved. The conditions of non-welding, insufficient welding and the like between the male and female sockets and the circuit board are avoided, and the connection reliability of the circuit board and the male and female sockets is improved.
