A method and apparatus for docking a test head to a peripheral. A docking pin () is moved past a projection () in a catch (). The docking pin is further moved until the catch rotates and the projection in the catch engages a notch or indentation () in the docking pin. A piston () is moved on to the catch so that the catch is prevented from rotating. The piston is further moved so that the test head is docked to the peripheral.

Method and apparatus for docking a test head with a peripheral

A test head manipulator system comprising a base structure, a main arm unit configured to support a test head and to be moved relative to the base structure, an actuator having a range of motion of L, and an enhancement mechanism positioned between the main arm unit and the actuator and configured such that movement of the actuator a first distance causes the main arm unit to move a second distance that is greater than the first distance. Additionally, a fluid control system for controlling a test head manipulator system. The pneumatic control system includes a regulator configured to controllably provide an output pressure to the main fluid actuator, and a second fluidly controlled actuator configured to adjust the regulator to modify the output pressure provided to the main fluid actuator. The second actuator is configured to be positively positioned in at least four operating modes with each operating mode causing the regulator to provide a different output pressure to the main fluid actuator.

Test head manipulator

A manipulator for translating a load along an axis of translation is provided. The manipulator comprises an outer column and a telescoping column positioned adjacent the outer column. The telescoping column is attached to the load and configured to translate the load along the axis of translation. At least one guiding member is mounted between the outer column and the telescoping column, wherein the guiding member is configured to guide the telescoping column as the telescoping column translates along the axis of translation.

Test head vertical support system

An apparatus for supporting a device, comprising a base assembly, a plurality of carrier columns extending from the base unit, and a plurality of vertical support plates, each vertically movable along a respective carrier column and including a pivotal device mounting bracket. A pneumatic unit including a piston rod is associated with each vertical support plate such that vertical motion of the piston rod controls vertical motion of the respective vertical support plate.
