PURPOSE:To hold flatness, and to improve operability of external appearance inspection of an electronic component, a screen printing, etc., by sucking a board to many sucking pads protruding from the upper surface of a plate. CONSTITUTION:In a board positioning apparatus 1, a suction port 3 is formed in a plate 2, and a tube 4 for sucking the inner area of the port 3 by a vacuum pump is mounted. Many holes 5 are formed in a matrix state on the upper surface of the plate 2 to communicate with the port 3. On the other hand, sucking pads 6 are respectively mounted in the holes 5. The pads 6b slightly protrudes from the upper surface of the plate 2 in this state, and are arranged in high density in the formed many holes 5. According to this, since a board 10 placed on the plate 2 is sucked to the many pads 6, it is not deflected, nor twisted, but held horizontally in excellent flatness. |
