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
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

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

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.
