CHANGZHOU FHD ELECTRONICS CO., LTD is a professional manufacturer in the field of ceramic components ,our products is widely used in household electrical appliances; mobile phones; computers; medical equipment; alarm system; pos machine ；access control system; toy; automobile; instrument and meter; electrical equipment; we can produce all kinds of piezo buzzers as long as you have the following details; welcome to consultation discussion.
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 temperatur 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.
(3)Low Temperature Test
