Test Condition
Lead terminals are immersed in rosin for
5 seconds and then immersed in solder bath
of 230 ±5°C for 2 ±0.5 seconds.
1) IR Reflow
Pre-heating conditions should be 140~160°C for
60 to 120 seconds. Ascending time up to
200°C should be longer than 30 seconds.
Heating conditions should be within 10 seconds
at 230°C min. Peak temperature should be
235°C. Then, place leave the buzzer in natural
conditions for 1 hour before measuring.
2) Soldering Iron
Soldering iron of 270 ±5°C should be placed
0.5mm above the buzzer’s electrode. Melting
solder through the soldering iron should be
applied to the electrode for 3±1 seconds. Then,
place the buzzer in natural conditions for
4 hours before measuring.
For 10 seconds, the force of 9.8N (1.0kg) is
applied to each terminal in axial direction.
The buzzer shall be measured after applying
a vibration amplitude of 1.55 mm with 10 to
55 Hz band of vibration frequency for 1 minute
to each of the 3 perpendicular directions for
2 hours.

Evaluation Standard
95% of the surface of the lead
pads must be covered with
fresh solder.
No interference in operation.
No damage or cutting off.
The value of oscillation
frequency/current consumption
should be ±10% of the initial
measurements. The SPL should
be within ±10dB compared with
the initial measurement.
