  • Using vibrations to position devices in a test system
    Patent number: 11353375
    Abstract: An example test system includes a tray to hold devices, where the devices include devices to be tested or devices that have been tested; a motor that is controllable to cause vibrations; and a component that couples the motor to the tray to cause the tray to vibrate in response to the vibrations of the motor.
    Type: Grant

  • Mechanism for clamping device interface board to peripheral
    Patent number: 6617867
    Abstract: A mechanism for attaching a device interface board (DIB) to a surface of a test head or peripheral includes first and second pulldown mechanisms attached to the surface and a substantially U-shaped actuator. Each of the pulldown mechanisms includes a rotating member coupled to a connecting member via a translation interface. The translation interface converts rotation of the rotating member into vertical movement of the connecting member. The U-shaped actuator has first and second ends respectively coupled to the rotating members of the first and second pulldown mechanisms. Swinging the U-shaped actuator through an arc rotates the rotating members and causes the connecting members to move vertically. A DIB that latches with the connecting members can thus be pulled down against the surface quickly and conveniently, with sufficient mechanical leverage for compressing large numbers of spring-loaded pins.
