The invention discloses board surface cleaning equipment for a printed circuit board, and relates to the technical field of cleaning equipment. The board surface cleaning equipment comprises a mounting frame, a conveying mechanism, a cleaning mechanism, a drying mechanism, a cooling recycle mechanism, a fixing mechanism and a heating mechanism, wherein the conveying mechanism is arranged at the lower end of the inner side of the mounting frame, the cleaning mechanism is arranged above one side of the conveying mechanism, and meanwhile the drying mechanism is arranged above the other side of the conveying mechanism; a cleaning box is arranged on one side of the cleaning mechanism, and the fixing mechanism is placed on the conveying mechanism; and the heating mechanism is fixedly installed on the vertical inner side wall, on one side of the drying mechanism, of the mounting frame. According to the board surface cleaning equipment for the printed circuit board, through the fixing mechanism, the conveying mechanism, the cleaning mechanism, the drying mechanism, the heating mechanism and the cooling recycle mechanism which are sequentially composed, automatic and efficient cleaning of the circuit board can be achieved, damage to the circuit board during cleaning is avoided, the circuit board can be dried through inert gas in a clean and closed environment, and dust pollution and oxygen oxidation are avoided.
