7. Reliability and Environmental Specification
7.1 Temperature test
Put the module in demo board which uses exit power supply, power on the module and
connect to mobile. Then put the demo in the ‐40℃ space for 1 hour and then move to +85℃
space within 1minute, after 1 hour move back to ‐40℃ space within1 minute. This is 1 cycle.
The cycles are 32 times and the units have to pass the testing.
7.2 Vibration Test
The module is being tested without package. The displacement requests 1.5mm and
sample is vibrated in three directions(X,Y,Z).Vibration frequency set as 0.5G , a sweep rate of
0.1 octave/min from 5Hz to 100Hz last for 90 minutes each direction. Vibration frequency set
as 1.5G, a sweep rate of 0.25 octave/min from 100Hz to 500Hz last for 20 minutes each
direction.
7.3 Desquamation test
Use clamp to fix the module, measure the pull of the component in the module, make sure
the module`s soldering is good.
7.4 Drop test
Free fall the module (condition built in a wrapper which can defend ESD) from 150cm
height to cement ground, each side twice, total twelve times. The appearance will not be
damaged and all functions OK.
7.5 Packaging information
After unpacking, the module should be stored in environment as follows:
Temperature: 25℃ ± 2℃
Humidity: <60%
No acidity, sulfur or chlorine environment
The module must be used in four days after unpacking.
