  • Patent number: 11450640
    Abstract: A wire bonding apparatus includes: a first tensioner which forms, nearer a wire supply side than a bonding tool, a first gas flow for applying a tension toward the wire supply side on a wire; a second tensioner which forms, between the first tensioner and a pressing part of the bonding tool, a second gas flow for applying a tension toward the wire supply side on the wire; and a control part which controls the first tensioner and the second tensioner. The control part implements control, in a predetermined period after a first bonding step for bonding the wire to a first bonding point, to turn off at least the second gas flow of the second tensioner among the first tensioner and the second tensioner or to make at least the second gas flow smaller than in the first bonding step.

  • Publication number: 20220208721
    Abstract: This wire bonding apparatus has a capillary, a movement mechanism moving the capillary, and a control unit controlling driving of the movement mechanism. The control unit at least causes execution of: a first process (trajectory a) of lowering the capillary, after a FAB is formed, to pressure bonding height at a first bonding point to form a pressure bonded ball and a column part at the first bonding point; a second process (trajectory b) of moving the capillary horizontally at the pressure bonding height after execution of the first process to scarp off the column part by the capillary; and a third process (trajectory c-k) of repeating a pressing operation at least once after execution of the second process, the pressing operation involving moving the capillary forward and lowering the capillary temporarily during movement so that the capillary presses down on a wire portion positioned over the pressure bonded ball.

  • Patent number: 8815732
    Abstract: After forming a pressure-bonded ball and a ball neck by bonding an initial ball to a pad, a capillary is moved upward, away from a lead, and then downward, thereby the ball neck is trodden on by a face portion that is on the lead side of the capillary. Subsequently, the capillary is moved upward and then toward the lead until the face portion of the capillary is positioned above the ball neck, thereby a wire is folded back toward the lead. Then, the capillary is moved downward such that a side of the wire is pressed by the capillary against the ball neck that has been trodden on. After the capillary is moved obliquely upward toward the lead and then looped toward the lead, the wire is pressure-bonded to the lead.
