5.1.2 Thermal Calibration and Controls
It is recommended that full and routine calibration of temperature measurement
equipment be performed before attempting to perform a temperature case
measurement of the Intel ® 5100 MCH Chipset. Intel recommends checking the meter
probe set against known standards. This should be done at 0 °C (using an ice bath or
other stable temperature source) and at an elevated temperature, around 80 °C (using
an appropriate temperature source).
Wire gauge and length also should be considered because 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: It is recommended to follow company standard procedures and wear safety items like
glasses for cutting the IHS and gloves for chemical handling.
Note: Ask your Intel field sales representative if you need assistance to groove and/or install
a thermocouple according to the reference process.
5.1.3 IHS Groove
Cut a groove in the package IHS according to the drawing given in Figure 6 .
Note: The center of the round at the end of the IHS groove should be at the center of the
package.
