Case Temperature Reference Metrology

Thermal/Mechanical Design Guide 77
D.4 Thermal Calibration and Controls
It is recommended that full and routine calibration of temperature measurement equipment be
performed before attempting to perform temperature case measurement of processors. Intel
recommends checking the meter probe set against known standards. This should be done at 0 ºC
(using ice bath or other stable temperature source) and at an elevated temperature, around 80 ºC
(using an appropriate temperature source).
Wire gauge and length also should be considered as some less expensive measurement systems
are heavily impacted by impedance. There are numerous resources available throughout the
industry to assist with implementation of proper controls for thermal measurements.
Note:
1. It is recommended to follow standard safety procedures and wear safety items like glasses for
cutting the IHS and gloves for chemical handling.
2. Ask your Intel field sales representative if you would like assistance to groove and/or install a
thermocouple according to the reference process.
D.5 IHS Groove
Cut a groove in the package IHS according to the drawing given in Figure 27.
