Thermocouple Attach Procedure
The procedure to attach a thermocouple with solder takes about 15 minutes to
complete. Before proceeding turn on the solder block heater, as it can take up to
30 minutes to reach the target temperature of 153 – 155 °C.
Note:
To avoid damage to the processor ensure the IHS temperature does not exceed
155 °C.
As a complement to the written procedure a video Thermocouple Attach Using Solder
– Video CD-ROM is available.

Thermocouple Conditioning and Preparation
7.
Use a calibrated thermocouple as specified in Sections
D.3.
8.
Under a microscope verify the thermocouple insulation meets the quality
requirements. The insulation should be about 1/16 inch (0.062 ± 0.030) from the
end of the bead (Figure

9.
Measure the thermocouple resistance by holding both contacts on the connector
on one probe and the tip of thermocouple to the other probe of the DMM
(measurement should be about~3.0 ohms for 36-gauge type T thermocouple).
10.
Straighten the wire for about 38 mm [1 ½ inch] from the bead.
11.
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
