64-bit Intel® Xeon™ Processor with 2MB L2 Cache Thermal/Mechanical Design Guidelines 63
C Quality and Reliability
Requirements
C.1 Intel Verification Criteria for the Reference Designs
C.1.1 Reference Heatsink Thermal Verification
The Intel reference heatsinks will be verified within specific boundary conditions using a TTV and
the methodology described in the Intel
®
Xeon™ Processor Family Thermal Test Vehicle User's
Guide
.
The test results, for a number of samples, are reported in terms of a worst-case mean + 3σ value for
thermal characterization parameter using real processors (based on the TTV correction offset).
C.1.2 Environmental Reliability Testing
C.1.2.1 Structural Reliability Testing
Structural reliability tests consist of unpackaged, board-level vibration and shock tests of a given
thermal solution in assembled state, as well as long-term reliability testing (temperature cycling,
bake test). The thermal solution should be capable of sustaining thermal performance after these
tests are conducted; however, the conditions of the tests outlined here may differ from the
customers’ system requirements.
C.1.2.2 Random Vibration Test Procedure
• Duration: 10 min/axis, 3 axes
• Frequency Range: 5 Hz to 500 Hz
• Power Spectral Density (PSD) Profile: 3.13 G RMS (refer to Figure C-1).
