The utility model relates to a vacuum chuck for PCB board, including bottom plate and a plurality of vacuum slot, offer the recess that is used for installing the suction nozzle on the bottom plate, install in the recess bottom movablely the suction nozzle bottom, and its top protrusion is outside the recess. Because the top protrusion of suction nozzle is outside the recess, when tight PCB boardis inhaled to the suction nozzle, the PCB board not can with bottom contact, avoid causing the problem that the friction harmd between PCB board and the bottom plate. 本实用新型涉及种用于PCB板的真空吸盘，包括底板和若干真空吸嘴，所述底板上开设有用于安装吸嘴的凹槽，所述吸嘴底端活动地安装在凹槽底部，其顶端凸出于凹槽外。由于吸嘴的顶端凸出于凹槽外，当吸嘴吸紧PCB板时，PCB板不会与底板接触，避免造成PCB板与底板之间摩擦损伤的问题。
