## Reliability Tests
|Temperature change|-40℃to +85 °C, MIL-STD 810G Method 503.5.
1.Room Temperature to -40 °C (2hours) 2.Storage for 2 hours at -40 °C 3.
-40 °C to 85 °C (2hours) 4. Storage for 2 hours at 85 °C 5. 85 °C to -40 °C
( 2hours) 6.Repeat from 2 to 5 for 5 times 7. -40 °C increase to room
temperature within 2 hours (Total 44 Hrs)
No loss of function after tests.|
|---|---|
|Storage test|-40°C to +85°C, MIL STD 810G Method 501.5 (high) Method 502.5 (low)
1.Room Temperature to -40°C within 2 hours 2.Storage for 24 hours at -
40°C; 3. -40°C to room temperature within 2 hours 4.Room Temperature
to +85°C within 2 hours 5.Storage for 24 hours at 85°C; 6. 85°C room
temperature within 2 hours(Total 56 Hrs) No loss
of function after tests.|
|Shock test|1.Three shocks in each direction shall be applied along the three mutually
perpendicular axes of the test specimen (18 shocks) 2.Peak value:
1,500g’s 3.Duration: 0.5ms 4.Waveform: Half si. No loss of function after
tests.|
|Drop test|Drop test (single device) for mounted device, the antenna needs to be
fixed to PCB and then assemble PCBA into the covers for the test, please
do the test with Armadillo antenna, only need the PCB and top/bottom
cover for the tests.|
|Vibration test|Random vibration input of 60 min/axis, all three perpendicular axis.
Transportation frequency 5-500 Hz using Fig 514.6C-I and Table 514.6-II of
MIL STD 810G section 514.6, performed only upon customer request., no
loss of function after tests.|
