Printed circuit board structure capable of increasing friction force of screw holes

The utility model relates to a printed circuit board structure capable of increasing friction force of a screw hole, which comprises at least one target screw position, the target screw position comprises the screw hole and at least one windowing bonding pad arranged around the screw hole, the distance between the windowing bonding pad and the target screw hole meets a first preset requirement, a solder paste layer is attached to the windowing bonding pad, and a solder paste layer is attached to the solder paste layer. The roughness of the surface of the solder paste layer meets a second preset requirement, the solder paste layer is an unsmooth coating formed on the windowing bonding pad after the surface of the windowing bonding pad is coated with solder paste and the printed circuit board is subjected to furnace passing, the printed circuit board further comprises target screws matched with the target screw positions, each target screw comprises a screw head and a screw rod, and the screw heads are matched
