1. Technical Parameter

Measuring condition

Part shall be measured under a condition (Temperature: 5～35℃, Humidity: 45%～85%R.H., Atmospheric pressure: 860 ～1060hPa) unless the standard condition (Temperature: 25±3℃, Humidity: 60±10%R.H. Atmospheric pressure: 860 ～1060hPa) is regulated to measure.

*Housing Material: Black PPS

Surface mounting condition

(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.

(2)Soldering pattern

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

(1)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.

(2)High Temperature Test

The part shall be capable of with standing a storage temperature of +80℃ for 96 hours.

(3)Low Temperature Test

The part shall be capable of with standing a storage temperature of ­-30℃ for 96 hours.

(4)Humidity Test

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

and expose to room temperature for 6 hours

(5)Temperature Shock Test

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

Total cycle: 10 cycles

(6)Drop Test

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

three sides, six plain.)

(7)Vibration Test

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

(8)Reflow Test

Use recommendable reflow soldering condition (as shown in 5.1)

No abnormality should be found after reflow

Good soldering to meet soldering requirements
