5.3 Probe Arm
Assembly
Reconfiguration
The following sections describe the procedures to reconfigure the probe arm assem-
blies of your probe station. These reconfigurations will not necessarily need to be
done daily, but you may find them essential for some research situations.
5.3.1 Installing a
Micro-manipulated
Translation Stage
(MMS-07)
Follow this procedure to add a probe arm stage to your probe station.
1. Use the micrometers and hand dial to center the x, y and z-axis stages in the
probe station.
2. Using a 3 mm hex driver, remove the four M4 screws on the arm stage plate if
present, and set the plate aside.
3. Using a 2.5 mm hex driver, remove the two M3 screws in the slide insert from the
bottom of the new stage (FIGURE 5-5).
4. Position the slide insert onto the arm stage location so that it is facing as illus-
trated (FIGURE 5-5) and secure the insert to the arm stage location.
5. Using a 3 mm hex driver, unscrew the four M4 screws from the arm port blank on
the vacuum chamber if present. Remove the blank and set it aside.
6. Clean the o-ring groove in the probe arm port (FIGURE 5-6). Clean, inspect and
lightly grease the o-ring with vacuum grease and place it in the groove.
7. Slide the stage onto the probe arm location, and carefully guide the cable and
probe arm through the arm port (FIGURE 5-6). Take care that the cable and probe
arm enter the radiation shield. The copper arm shield braids go between the
chamber and radiation shield.
