Surface mounting condition

(1)Reflow soldering

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 temperatur Gradient such as rapid heating or cooling may cause electrical failures and mechanical damages of the devices

(2)Soldering pattern
