Piezo Buzzer Surface mounting condition
(1)Piezo Buzzer Reflow soldering
Recommendable reflow soldering condition is as follows.
Piezo Buzzer 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.
(2)Piezo Buzzer Soldering pattern
Piezo Buzzer Reliability Test
