D.3 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. Intel recommends checking the meter probe set against known
standards. This should be done at 0ºC (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.
NOTES:
1. It is recommended to follow company standard 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 need assistance to groove and/or
install a thermocouple according to the reference process.
D.4 IHS Groove
Cut a groove in the package IHS according to the drawing provided in either Figure 35
or
Figure 36. The alternate groove orientation in Figure 36 allows the thermocouple
to be routed toward the latch side of the processor retention lid of the 775LGA socket.
