  • FLEXURE, HEAD GIMBAL ASSEMBLY AND DISK DRIVE UNIT WITH THE SAME, AND MANUFACTURING METHOD THEREOF
    Publication number: 20140293485
    Abstract: A flexure for a suspension of a head gimbal assembly includes a substrate layer, a dielectric layer formed thereon, a conducting layer formed on the dielectric layer, and an insulating cover layer covered on the conducting layer, wherein at least one window is configured at a surface of the insulating cover layer thereby a portion of the conducting layer is exposed, and an antistatic adhesive is adhered to at least one side wall of the window and contacted with the conducting layer. The new structure of the flexure can avoid or eliminate electro-static discharges enduringly without dipping water. A head gimbal assembly and a disk drive unit with the same, a manufacturing method for the flexure are also disclosed.
