  • Patent number: 7877870
    Abstract: The tip end of the bonding tip is defined between first and second edges. A first inclined surface gets remoter from a first terminal at a position remoter from the first edge. The second inclined surface likewise gets remoter from the first terminal at a position remoter from the second edge. The solder is contoured by first and second contours on the first terminal. The second terminal is located on the solder between the first and second contours. The tip end of the bonding tip is urged against the second terminal. Heat is transferred from the bonding tip to the solder. The melted solder spreads into gaps between the second terminal and the first and second inclined surfaces. The solder is thus prevented from spreading outside the contour of the first terminal. This results in a reliable avoidance of a short circuit between the adjacent first terminals.

  • Publication number: 20070279807
    Abstract: A first flexible printed wiring board is attached to the supported end of a carriage. First terminals are exposed on the first flexible printed wiring board. A second flexible printed wiring board extending from a head slider toward the supported end of the carriage. The second flexible printed wiring board is overlaid on the first flexible printed wiring board. Second terminals are exposed on the second flexible printed wiring board. The second terminals are bonded to the first terminals. A step defines a wall surface facing the edge of the second flexible printed wiring board on the first flexible printed wiring board. A depression is defined on the first flexible printed wiring board. The second flexible printed wiring board is received in the depression, the second terminal can accurately be positioned on the first terminal in a facilitated manner.
