4.1Reliability Requirements
If an attached heatsink is implemented due to a severe component local operating environment, the reliability requirements in Table 4 are recommended. Each motherboard, heatsink, and attach combination may vary the mechanical loading of the component. It is recommended that the user carefully evaluate the reliability of the completed assembly prior to use in high volume.
