3.Electrical And Acoustical Measuring Condition
Recommended Setting
Surface mounting condition
Reflow soldering
Recommendable reflow soldering condition is as follows.
Note:
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. 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.Application:
