A printed circuit board (PCB), comprising a board body (10), two sets of bonding pads adjacently disposed on the board body (10) in a first direction; each set of the bonding pads comprises a first bonding pad (31) and a second bonding pad (32) adjacently disposed in a second direction perpendicular to the first direction, and the first bonding pad (31) and the second bonding pad (32) have different specifications. The PCB can be compatible with the welding of electronic components having different sizes, reduce PCB area, improve utilization of the PCB, while preventing defects caused by component shifting due to excessive solder paste in the manufacturing process. |
