PROBLEM TO BE SOLVED: To provide a cleaner for a printed circuit board by which clogging of a hole in a printed circuit board 1 can be surely removed. SOLUTION: In the cleaner for a printed circuit board, a conveyor belt is covered with a mesh sheet that is formed by weaving extremely thin longitudinal threads and weft yarns, and an air is jetted over the printed circuit board placed on the conveyor belt through an air nozzle. Tight longitudinal treads and weft yearns are interposed with an interval of several longitudinal threads and weft yarns in the mesh sheet to weave them each other like bellows for reinforcement. The conveyor belt is made permeable, and a suction duct is made open under an upper track of the conveyor belt. COPYRIGHT: (C)2004,JPO
