Wafer Probers and Connection with Testhead
Connecting with Testhead
Personality board
The personality board and probe card are used to interface between the measurement pins of the testhead and the
probe needles.
Agilent Technologies provides the Agilent E3145A/B personality board for the 4072A/B tester.
This personality board is designed so that all testhead measurement pins can contact the pads on this board.
The personality board must be fixed on the wafer prober. See Figure 3-9.
NOTE Agilent Technologies recommends the use of the direct docking probe card when using the
4073A/B. The 4073A/B may not fully perform if a personality board or extension cable fixture is
used.
