Thermal Solution Quality and 
Reliability Requirements
9.1
Collaboration Heatsink Thermal Verification
Each motherboard, heatsink and attach combination may vary the mechanical loading 
of the component. Based on the end user environment, the user should define the 
appropriate reliability test criteria and carefully evaluate the completed assembly prior 
to use in high volume. The Intel collaboration thermal solution will be evaluated to the 
boundary conditions in 
The test results, for a number of samples, are reported in terms of a worst-case mean 
+ 3σ value for thermal characterization parameter using the TTV. 
9.2
Mechanical Environmental Testing
Each motherboard, heatsink and attach combination may vary the mechanical loading 
of the component. Based on the end user environment, the user should define the 
appropriate reliability test criteria and carefully evaluate the completed assembly prior 
to use in high volume. Some general recommendations are shown in 
The Intel collaboration heatsinks have been tested in an assembled LGA1156 socket 
and mechanical test package. Details of the environmental requirements, and 
associated stress tests, can be found in 
 are based on speculative use 
condition assumptions, and are provided as examples only.
Notes:
1.
It is recommended that the above tests be performed on a sample size of at least ten assemblies from 
multiple lots of material.
2.
Additional pass/fail criteria may be added at the discretion of the user.
