6. IFM Imaging Procedure Place whipple grid on sample holder.
Image 5 um square at a corner with IFM.
Remove IFM head and replace with optical head.
Place optical reticle on 5 um square corner
Replace positioning reticle with sample.

7. IFM Imaging Procedure Move the sample to the desired testing location.
Remove optical head and replace with IFM head.
Image sample or begin force/creep profile.

8. Tip Placement Apparatus
Z-stage
X-Y Stage

9. Tip Placement Apparatus

10. Tip Placement Procedure
Place sensor on X-Y stage.
Place tip in forceps and connect to z-stage.
Carefully apply epoxy to tip base and desired sensor position.
Move tip into contact with the sensor.
Turn on cartridge heater. (Not pictured)

11. Tip Placement Procedure
After curing gradually lift (approx. 1 mm) the sensor off the X-Y stage.
Disconnect forceps from the tip.
