Test method/procedure |
| 8.1 |
The heat sink assembly was mounted onto the shaker table and subjected to a
sinusoidal vibration test as follows: |
|
|
Frequency range |
8 Hz to 100 Hz |
|
|
Vibration amplitude |
± 3g pk |
|
|
Rate of change of frequency |
1 Octave per minute |
|
|
Test duration |
20 minutes |
| 8.2 |
During the above 20 minute period the heat sink assembly was observed
visually for evidence of the max mounts becoming detached. |
| 8.3 |
The procedures described in 8.1 and 8.2 above were repeated such that
vibration test was conducted in all three mutually perpendicular axes. |
| 8.4 |
The heat sink assembly was then subjected to a shock test as follows: |
|
|
Shock pulse envelope |
112 sine |
|
|
Period |
6 ms |
|
|
Amplitude |
5 g |
|
|
Number of shocks |
3 |
|
|
Application |
3 shocks per sense per axis |
| 8.5 |
During the above 20 minute period the heat sink assembly was
observed visually for evidence of the max mounts becoming detached. |
| 9. |
Test results |
| 9.1 |
The max clips did not break free from the heat sink assembly. No physical degradation was observed. |
