Cobal 250 Manipulator

Counter-balanced Universal Manipulator for the Test Floor

The Cobal 250 offers the best-in-class range of motion for universal manipulators with seven degrees of motion. Separate linear movements make it easier for the operator to dock, undock, and redock the test head in seconds. In combination with inTEST EMS docking, the Cobal 250 is compatible with testers for both Wafer Sort and Final Test, minimizing the time and cost when moving a tester between Sort and Final Test.

Less setup time = less downtime.

Key Features

Make each motion independently and separately from all other motions.
Low-force compliance motions accurately position the test head so that docking can be smoothly and easily engaged.
Range of motion allows the user the most flexibility in docking to the widest range of peripheral equipment
