  • Electrical connection for testing head gimbal assemblies
    Patent number: 7684948
    Abstract: A method for forming an electrical connection with head gimbal assembly. At least a portion of an unmounted head gimbal assembly is placed on a surface. The unmounted head gimbal assembly includes a flexible portion, the flexible portion includes contact pads, and the surface includes electrical contacts and slots. A section of the flexible portion is pushed against the surface, and the contact pads are interconnected with the electrical contacts using a clamp assembly controlled by a computer. The clamp assembly includes a clamp with pins, and the interconnecting includes engaging the pins with the slots, rotating the clamp towards the surface, and clamping the contact pads against the electrical contacts.

  • Solderless electrical connection for testing head gimbal assemblies
    Patent number: 7509224
    Abstract: A method for making an electrical connection between a head gimbal assembly and a tester. The method includes providing a solderless connector including a housing with bores extending from a first side of the housing to a second opposed side of the housing, and conductors within the bores of the housing. The conductors have a first end protruding from the first side of the housing and a second end protruding from the second side of the housing. The solderless connector is positioned so the first end of the conductor engages the conductive pad of the tester, and a clamp is applied to the first side of the electrical contact on the head gimbal assembly to urge the second side of the electrical contact against the second end of the conductor on the solderless connector.
