The utility model discloses a base plate for PCB (printed circuit board) screen printing, which comprises an anti-impact device, the anti-impact device is arranged in a base and can buffer impact force received by the base plate above, the anti-impact device mainly comprises a sliding block and a fluid bin, the upper surface of the sliding block is connected with the base plate in a sliding manner, and the fluid bin is connected with the base plate in a sliding manner. The base plate for PCB screen printing is provided with the anti-impact device, when a circuit board is impacted by a printing device, the base plate on the lower surface can be driven to move downwards, at the moment, the base plate can drive a fluid bin and a sliding block below to move downwards, and fluid in the fluid bin can extrude a piston rod to move downwards; the piston rod is arranged on the base plate, so that movement of the base plate is hindered through contact between fluid and the piston rod, meanwhile, the sliding blocks move
