PURPOSE:To avoid short-circuit failures caused by bends of bonding wires by a method wherein a 2nd guide rail which guide a frame is provided and the 2nd guide rail is made of material whose friction coefficient is smaller than the coefficient of the material of a carrying-out belt and a positioning pusher which pushes the frame to the conveying direction and can be turned freely is provided on the side of a carrying-in belt. CONSTITUTION:A pusher 13 is turned clockwise by the repulsion force of a coil spring 16 and provided above a frame conveying plane. After the driving of a belt 1 is stopped and a frame is transferred to a wire bonding position 5 by a feeder and the wire bonding is finished, the frame is transferred onto a guide rail 11 by a feeder. The guide rail 11 is provided above a belt 4. Then the guide rail 11 is made to descend by a driving apparatus 12 to put the frame after the wire bonding on the belt 4 and the frame after the wire bonding is conveyed to a next process by driving the belt 4. Thus, the frame can be conveyed before and after the wire bonding. |
