5.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
a)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.
B )High Temperature Test
The part shall be capable of with standing a storage temperature of +85℃ for 96 hours.
c)Low Temperature Test
The part shall be capable of with standing a storage temperature of -40℃ for 96 hours.
d)Humidity Test
Temperature:+40℃±3℃ Relative Humidity:90%~95% Duration: 48 hours and expose to room temperature for 6 hours
e)Temperature Shock Test
Temperature:60℃ /1hour→ 25℃/3hours→-20℃/1hour→ 25℃/3hours (1cycle)
Total cycle: 10 cycles
f)Drop Test
Standard Packaging From 75cm(Drop on hard wood or board of 5cm thick, three sides, six plain.)
g)Vibration Test
Vibration:1000cycles /min. Amplitude:1.5mm, Duration: 1 hour in each 3 axes
h)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


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.

6. Surface mounting condition

6.1 Reflow 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 socks 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.
