5. This device is very thin device and should be handled with caution for mechanical stress. The rate of distortion
applied to the device should become below 2000
μ
.
Note1
If the rate of distortion exceeds 2000
μ
, the
characteristic of a device may be degraded and it may result in failure.
Figure 2. Direction of substrate and stress
The substrate that mounted the device is on a stand with a support width of 24 mm.
The device is turned downward. The stress is applied from a top.

The relation of the distortion and the bend changes with several conditions, such as a size of substrate and
so on.
