The invention discloses a printed circuit board (PCB) solder resist plug hole screen board. The screen board comprises a screen frame, an elastic pad, a lock fastener and an aluminum sheet, wherein a through hole corresponding to a PCB hole is formed in the aluminum sheet; a plurality of first penetrating holes are formed in the screen frame; a plurality of second penetrating holes corresponding to the first penetrating holes are formed in the edge of the aluminum sheet; a plurality of third penetrating holes corresponding to the second penetrating holes are formed in the elastic pad; the lock fastener are inserted into the first penetrating holes, the second penetrating holes and the third penetrating holes in a detachable mode; and the screen frame, the elastic pad and the aluminum sheet are attached to and locked with one another though the lock fastener. By the PCB solder resist plug hole screen board, the aluminum sheet can be conveniently disassembled, so that the PCB boards with different hole positions can be adapted, the manufacturing cost of the screen board can be reduced, and the corresponding accuracy of the through hole and the PCB hole is improved.
