Abstract
An example manipulator for transporting a test head includes: a tower having a base and a track, with the track being vertical relative to the base; an arm to enable support for the test head, with the arm being connected to the track to move the test head vertically relative to the tower; one or more motors to drive movement of the arm along the track; and pneumatic cylinders to control movement of the arm to cause the test head to apply an amount of force to a peripheral device.
Claims20
A manipulator for transporting a test head, comprising:
- a tower having a base and a track, the track being vertical relative to the base;
- an arm to enable support for the test head, the arm being connected to the track to move the test head vertically relative to the tower;
- one or more motors, coupled to the arm, to drive movement of the arm along the track;
- and
- pneumatic cylinders, coupled to the arm, to control movement of the arm to cause the test head to apply a compliance force in a direction of an interface device to cause the test head to connect to the interface device.
2 more elements
A system comprising:
- a test head configured to interface to a device interface board (DIB) connected to a device under test (DUT), the test head comprising electronics to test the DUT;
- and
- a manipulator that is connectable to the test head to bring the test head into contact with the DIB, the manipulator comprising:
- an arm to enable support for the test head, the arm being configured to move vertically relative to the DIB;
- one or more motors, coupled to the arm, to drive vertical movement of the arm;
- and
- pneumatic cylinders, coupled to the arm, to control movement of the arm to cause the test head to apply a compliance force in a direction of the DIB to cause the test head to connect to the DIB.
