摘要： A method for testing head gimbal assemblies includes picking a first head gimbal assembly and holding the first head gimbal assembly with a first an end effector. The first end effector and the picked head gimbal assembly are positioned adjacent a nest using at least one actuator, and the first picked head gimbal assembly is released from the end effector to the nest. The first head gimbal assembly is tested on the nest by reading from and/or writing to a rotating disc. A second head gimbal assembly is held with a second end effector at the same time the first end effector holds the first head gimbal assembly.

摘要： 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.

摘要： A device comprises a mounting surface configured to mount a head gimbal assembly (HGA), a housing that pivots relative to the mounting surface, and a mechanism coupled to the housing that deflects the HGA when the housing pivots relative to the mounting surface. For example the mechanism may be a pneumatically actuated finger that pulls the HGA towards the housing. The device may be used to load the HGA on a rotating test disc. Once loaded on the test disc, the HGA is supported only by the mounting surface and an air bearing at an interface of a slider of the HGA and the test disc. Embodiments of the invention may provide precise and repeatable positioning of the HGA because dimensional tolerances and vibrations in the mechanism are not transferred to the HGA once it is loaded on the test disc.

摘要： An assembly comprises a flex circuit including a first set of electrical contacts on a first side of the flex circuit and a compliant support backing adjacent a second side of the flex circuit and opposite the set of electrical contacts. The first set of electrical contacts is configured to connect to a second set of electrical contacts on an electronic component. The compliant support backing includes a set of support elements that individually support the first set of electrical contacts to increase the contact pressure between the first set of electrical contacts and the second set of electrical contacts when the flex circuit is connected to the electronic component. Embodiments may provide robust electrical contracts which provide a reliable connection useful for testing electronic components, such as head gimbal assemblies.

摘要： An assembly for testing a head gimbal assembly (HGA) comprises a support platform configured to hold a base plate of the HGA. A base plate of the HGA is mounted on the support platform. The assembly further comprises a channel with an opening adjacent to a tail of the HGA and a vacuum source connected the channel. The vacuum source creates a negative pressure in the channel to secure the tail of the HGA to the opening of the channel. Embodiments of the invention may be useful to inhibit vibration in the tail of an HGA, which may also reduce vibration in the head of the HGA. Reducing vibration in the head of the HGA may increase the accuracy and precision of tests performed on the HGA using the assembly.
