What it is

The Signatone S-750 is a joystick micropositioner for probing and contacting small electrical targets on devices under test. The S-750 uses a magnetic base and a compact probe-holding body.[1][2]

How it works

The S-750 has a motion ratio, a scan area, and a spring probe clamp that is electrically isolated from the positioner body. The S-750 also uses a magnetic base and a removable extension rod option for probe placement control.[1][2]

Where it fits in the process flow

The S-750 is designed for large-area structures such as pads and for situations where space is limited and multiple probes must be placed on one device. The S-750 is used for failure analysis, pad probing, RF biasing, resistivity measurements, MEMS test, and high-density probe placement.[2][3]

Applications

The S-750 is intended for large-area structures and probing targets as small as 1 mil. The S-750 supports probe tip holders and probe tips selected for different probe styles and tip materials.[1][2]

  • contacting larger area structures (pads)
  • placing multiple probes down on one device when platen space is limited
