7.0Reliability Guidelines
Each motherboard, heatsink, and attach combination may vary the mechanical loading of the component. The user should carefully evaluate the reliability of the completed assembly prior to use in high volume. Some general recommendations are shown in Table 8.
Table 8. | Reliability Requirements |
| |
|
|
|
|
Test1 |
| Requirement | Pass/Fail Criteria2 |
Mechanical Shock | 50 g, board level, 11 ms, three shocks/axis | Visual Check and Electrical Functional Test | |
|
|
| |
Random Vibration | 7.3 g, board level, 45 minutes/axis, 50 Hz to 2000 Hz | Visual Check and Electrical Functional Test | |
|
|
|
|
Temperature Life |
| 85 °C, 2000 hours total, checkpoints at 168, 500, 1000, | Visual Check |

Notes:
1.The above tests should be performed on a sample size of at least 12 assemblies from three lots of material.
2.Additional pass/fail criteria may be added at the discretion of the user.
