Dual-Core Intel® Xeon® Processor 5100 Series Thermal/Mechanical Design Guide 83
Quality and Reliability Requirements
2. Heatsink remains seated and its bottom remains mated flatly against the IHS
surface. No visible gap between the heatsink base and processor IHS. No visible tilt
of the heatsink with respect to the retention hardware.
3. No signs of physical damage on baseboard surface due to impact of heatsink.
4. No visible physical damage to the processor package.
5. Successful BIOS/Processor/memory test of post-test samples.
6. Thermal compliance testing to demonstrate that the case temperature specification
can be met.
D.1.2.4 Recommended BIOS/Processor/Memory Test Procedures
This test is to ensure proper operation of the product before and after environmental
stresses, with the thermal mechanical enabling components assembled. The test shall
be conducted on a fully operational baseboard that has not been exposed to any
battery of tests prior to the test being considered.
Testing setup should include the following components, properly assembled and/or
connected:
• Appropriate system baseboard.
• Processor and memory.
• All enabling components, including socket and thermal solution parts.
The pass criterion is that the system under test shall successfully complete the
checking of BIOS, basic processor functions and memory, without any errors. Intel PC
Diags is an example of software that can be utilized for this test.
D.1.3 Material and Recycling Requirements
Material shall be resistant to fungal growth. Examples of non-resistant materials
include cellulose materials, animal and vegetable based adhesives, grease, oils, and
many hydrocarbons. Synthetic materials such as PVC formulations, certain
polyurethane compositions (e.g. polyester and some polyethers), plastics which contain
organic fillers of laminating materials, paints, and varnishes also are susceptible to
fungal growth. If materials are not fungal growth resistant, then MIL-STD-810E,
Method 508.4 must be performed to determine material performance.
Material used shall not have deformation or degradation in a temperature life test.
Any plastic component exceeding 25 grams should be recyclable per the European Blue
Angel recycling standards.
The following definitions apply to the use of the terms lead-free, Pb-free, and RoHS
compliant.
Lead-free and Pb-free: Lead has not been intentionally added, but lead may still
exist as an impurity below 1000 ppm.
RoHS compliant: Lead and other materials banned in RoHS Directive are either (1)
below all applicable substance thresholds as proposed by the EU or (2) an approved/
pending exemption applies.
Note: RoHS implementing details are not fully defined and may change.
