Model 70PTE Wire Pull Tester provides an exceptionally convenient means to place a hook under the arch of a bonded wire and then lower the wire under microprocessor control to measure tensile strength, either destructively or non-destructively. Embodied in this series is a new and unique West·Bond three-axis micromanipulator in which the entire mechanism is arrayed above the work plane, so that there is now no limit to the size of the work piece. The X, Y, and Z axes are straight-line and purely orthogonal, and each is braked pneumatically during the workstation pull stroke. Dual counterweights balance the pantograph arm and the tool support individually, complemented by an adjustable spring to counterbalance the hook tool assembly. The large work platform moves up and down in extremely small steps about a simple pivot while a load cell measures the force of the wire on the hook.
