Adapter board and manufacturing method therefor, and board card connecting structure

A manufacturing method for an adapter board, wherein the adapter board comprises a main body (1), perforations (2) are provided in a top face of the main body (1), and the perforations (2) are configured to be in plug-in fit with a plug of the connector (5);

• pads (3) are provided on a bottom face of the main body (1), and the pads (3) are configured to be soldered to the board card (6);
• row numbers, represented by r, and column numbers, represented by n, of the perforations (2) and the pads (3) are the same, and the perforations (2) have a one-by-one correspondence with the pads (3);
• the main body (1) further comprises a line passing area located between two adjacent columns of pads (3);
• and a column spacing of the perforations (2) in the top face of the main body (1) is represented by P, and a column spacing of the pads (3) on two sides of the line passing area is represented by M, M−P≥H, and H represents a minimum spacing allowed between adjacent differential lines (7) of the board card (6), wherein the method comprising:
• manufacturing a main body (1);
• processing perforations (2) in a top face of the main body (1), whereby a column spacing of the perforations (2) in the top face is represented by P;
• and
• processing pads (3) on a bottom face of the main body (1), whereby a column spacing of the pads (3) on two sides of a line passing area of the main body (1) is represented by M, wherein M−P≥H, H is representing a minimum spacing allowed between adjacent outgoing lines of the board card (6), row numbers and column numbers of the perforations (2) and the pads (3) are the same, and the perforations (2) have a one-by-one correspondence with the pads (3).
