8. Place the processor under the microscope unit (similar to the one used in
Figure 36) to
continue with the process. It is also recommended to use a fixture (like a processor tray or a
plate) to help hold the unit in place for the rest of the attach process.
9. Press the wire down about 6 mm [0.125”] from the thermocouple bead using the tweezers.
Look in the microscope to perform this task. Place a piece of Kapton tape to hold the wire
inside the groove (
Figure 33). Refer to Figure 34 for detailed bead placement.

10. Using the micromanipulator, install the needle near to the end of the groove on top of the
thermocouple. Using the X, Y, and Z axes on the arm place the tip of the needle on top of the
thermocouple bead. Press down until the bead is seated at the end of the groove on top of the
step (see
Figure 34 and Figure 35).
