5.Surface mounting condition
5.1Reflow soldering
Recommendable reflow soldering condition is as follows.
Note: (1) In automated mounting of the SMD sound transducers on PCB, any bending, expanding
and pulling forces or shocks against the SMD sound transducers shall be kept minimum
to prevent them from electrical failures and mechanical damages of the devices.
(2) In the reflow soldering, too high soldering temperatures and too large temperature
Gradient such as rapid heating or cooling may cause electrical failures and mechanical
damages of the devices.
