PURPOSE:To provide the method of setting the capillary in a wire bonding device which materializes the highly accurate positioning of the capillary. CONSTITUTION:This is a method of setting the capillary in a wire bonding device equipped with a camera 3 for pattern recognition, and comprises a process of making a bruise 2a on the target 2 with the top of a capillary 1 by lowering the this capillary 1 arranged above the target 2, a process of reading the target 2 given a bruise 2a with a camera 3 for pattern recognition and deducing the center P1 of the target 2 and the center P2 of the bruise 2a, based on the image read, and a process of calculating the quantities DELTAX and DELTAY of dislocation between the center P1 of the target 2 and the center P2 of the bruise 2a, and compensating the position of the capillary 1, based on the quantities DELTAX and DELTAY of dislocation being calculated. |
