Surface mounting condition

(1)Reflow soldering

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) 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

Test Resonant frequency, 1/2 duty Square wave.

(2)High Temperature

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