摘要： PROBLEM TO BE SOLVED: To perform satisfactory wire bonding by reducing feeding abnormality of a wire. SOLUTION: In a wire bonding technique, in which an electrode pad of a semiconductor chip mounted on a lead frame and a lead are connected by a conductive wire 14, a vibration applying means 24 is provided in the vicinity of the wire feeding portion of a wire spool 21 around which a wire 14 is wound, and vibrations are applied to the wire 14 fed from the wire spool 21 by the vibration applying means device 24. The wire fed from the wire spool 21 is supplied to a capillary by the action of wire tension and is utilized to connect the electrode pad and the lead of the semiconductor chip. Accordingly, clinging of wound wires around the wire spool 21 is unfastened satisfactorily, and the wires can be supplied stably. Consequently, a feeding abnormality of a wire and the bending of the wire 14 resulting from it are decreased and the quality and a yield of a semiconductor device are improved. Furthermore, the working ratio of the semiconductor device can be improved.

摘要： PURPOSE:To enable closing motion during opening motion and opening motion during closing motion by providing an operational lever and a slide switch with self locking mechanism to a moving base. CONSTITUTION:When switching from the opening motion to a closing motion during the opening motion being executed, the operational lever 11 is pushed during the opening motion, then a self locking mechanism 4a is shifted backward and is self-locked, and consequently, the direction of the current flowing through a dedicated motor 1 is reversed. Therefore, the motor 1 begins to rotate counterclockwise, and a moving base 9 starts to act the closing motion. On the contrary, when switching from the closing motion to the opening motion during the closing motion, an operational lever 11 is pushed toward the direction of arrow A. Then, the self locking mechanism 4a is shifted forward and is self- locked, and the motor 1 begins to rotate clockwise. Therefore, the moving base 9 starts an opening motion.

摘要： PROBLEM TO BE SOLVED: To prevent poor wire bonding due to erroneous setting of the orientation of a lead frame, by detecting whether a lead frame judging part exists in specified orientation area during detecting an image to judge the correctness of the lead frame setting orientation. SOLUTION: When a lead frame is in a forward frame state, a judging region 42 locates in a pilot hole 39 with a dark image. When in a reverse frame state, the judging region 42 locates at a support metal plate 35b constituting the lead frame with a bright image taken by a camera. Hence, a controller can automatically detect and judge whether the lead frame setting orientation is in the forward or reverse condition after processing the image, and this is visible on a monitor TV screen. Thus, it is possible to prevent poor wire bonding.
