  • Patent number: 8179639
    Abstract: Head gimbal assemblies for data storage systems are provided. Some embodiments include a dielectric layer having a first and a second side. A first conductive layer is on the first dielectric layer. The first conductive layer includes a pad and a trace. A second conductive layer is on the second dielectric side. A via extends from the first dielectric layer side to the second dielectric layer side. The via electrically connects the first conductive layer to the second conductive layer.

  • Publication number: 20030090839
    Abstract: The present invention includes an improved suspension assembly comprises a suspension including a load beam and a gimbal, a FOS having a polymer portion (or flex circuit) and a trace portion, wherein the FOS is connected to the suspension. The present invention further includes a slider that is electrically connected to a ground trace and the ground trace is further electrically connected to the suspension. The present invention also includes a plateau gimbal, which comprises of a portion of the ground trace positioned between the flex circuit and the slider thereby elevating the slider to the level of the bond pads on the FOS.
