PROVIDED IS A BONDING CAPILLARY (110) INCLUDING A BODY (10) HAVING A TIP SURFACE (50) THAT PERFORMS WIRE BONDING. THE TIP SURFACE (50) HAS MICROSCOPIC ASPERITIES. PEAKS OF THE ASPERITIES ARE LESS SHARP THAN VALLEYS OF THE ASPERITIES. IN THE BONDING CAPILLARY (110), WHEN SEEN IN A DIRECTION PERPENDICULAR TO THE TIP SURFACE (50), THE AREA OF THE PEAKS IS GREATER THAN THE AREA OF THE VALLEYS. (FIG. 1) |
