  • Magnetic disk drive, wiring connection structure and terminal structure
    Patent number: 7724478
    Abstract: Terminals of a flexible printed circuit board and terminals of a wiring trace in a head suspension assembly are to be connected with each other by soldering without causing a soldering defect. In an embodiment, a terminal structure of a multi-connector in a wiring trace which includes an insulating layer and a conductor pattern portion formed on a surface of the insulating layer is provided with exposed portions of terminals exposed from apertures formed in part of the insulating layer and is also provided with lining portions adjacent to the exposed portions in a longitudinal direction of the conductor pattern portion and bonded to the insulating layer. Even if terminals of the multi-connector are cracked when soldered, not only conductivity is ensured, but also it is possible to strengthen the terminals, because the lining portions of the terminals are bonded to the insulating layer.
    Type: Grant
    Filed: March 27, 2008
    Date of Patent: May 25, 2010
    Assignee: Hitachi Global Storage Technologies Netherlands B.V.
