    3. Electrical And Acoustical Measuring Condition

    Recommended Driving Circuit

    Resonant frequency, 1/2 duty cycle. Square wave.Signal amplitude should be large enough tosaturate the transistor.

    Recommended Setting

     

    4.Frequency Response

    3Vo-p 50% duty Square wave,10cm

     

    5. Surface mounting condition

    5.1 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 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.

    5.2 Recommended Soldering pattern

    6.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→-30℃/1hour→ 25℃/3hours (1cycle)

    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

    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.
