5.Piezo Buzzer Surface mounting condition

5.1 Piezo Buzzer Reflow soldering

Recommendable reflow soldering condition is as follows.

Piezo Buzzer 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.

6.Piezo Buzzer Reliability Test

After any following tests the part shall meet specifications without any degradation in

appearance and performance except SPL. SPL shall not deviate more than -10 dB

from the initial value


6.1Piezo Buzzer Ordinary Temperature Life Test

The part shall be subjected to 96 hours at 25±10℃. Input rated voltage

Resonant frequency, 1/2 duty Square wave.


6.2Piezo Buzzer High Temperature Test

The part shall be capable of with standing a storage temperature of +85℃ for 96 hours.


6.3Piezo Buzzer Low Temperature Test

The part shall be capable of with standing a storage temperature of ­-40℃ for 96 hours.


6.4Piezo Buzzer Humidity Test

Temperature:+40℃±3℃ Relative Humidity:90%~95% Duration: 48 hours

and expose to room temperature for 6 hours


6.5Piezo Buzzer Temperature Shock Test

Temperature:60℃ /1hour→ 25℃/3hours→-20℃/1hour→ 25℃/3hours (1cycle)

Total cycle: 10 cycles


6.6Piezo Buzzer Drop Test

Standard Packaging From 120cm(Drop on hard wood or board of 5cm thick,

three sides, six plain.)


6.7Piezo Buzzer Vibration Test

Vibration:1000cycles /min. Amplitude:1.5mm, Duration: 1 hour in each 3 axes


6.8Piezo Buzzer Reflow Test

Use recommendable reflow soldering condition (as shown in 5.1)

(1) No abnormality should be found after reflow

(2) Good soldering to meet soldering requirements


Piezo Buzzer Note:

As this product is not protected from foreign material entering, please make sure that any foreign materials (e.g. magnetic powder, washing solvent, flux, corrosive gas) do not enter this product in your production processes. The functional degradation (e.g. SPL down) may occur if foreign material enter it.
