5. Using the microscope and tweezers, bend the tip of the thermocouple at
approximately 10 degree angle by about 0.8 mm [.030 inch] from the tip
(Figure 36).

Thermocouple Attachment to the IHS

6. Clean groove and IHS with Isopropyl Alcohol (IPA) and a lint free cloth removing
all residues prior to thermocouple attachment.
7. Place the thermocouple wire inside the groove; letting the exposed wire and bead
extend about 1.5 mm [0.030 inch] past the end of groove. Secure it with Kapton*
tape (Figure 37). Clean the IHS with a swab and IPA.
8. Verify under the microscope that the thermocouple wires are straight and parallel
in the groove and that the bead is still bent.
