Test Condition
Lead terminals are immersed in rosin for
5 seconds and then immersed in solder bath
of 270 ±5°C for 2 ±0.5 seconds.
1) IR Reflow
Pre-heating conditions should be 150~200°C for
60 to 180 seconds. Ascending time up to
245°C should be longer than 55 seconds.
Heating conditions should be within 20 to 40
seconds at 245°C min. Peak temperature
should be lower than 255°C. The transducer
should be measured after 1 hour in normal
conditions.
2) Soldering Iron
A soldering iron of 270±5°C should be placed
0.5mm away from the electrode of the
transducer. Melted solder should be applied to
the electrode for 3±1 seconds. The transducer
should be measured after 4 hours in normal
conditions.
For 10 seconds, the force of 9.8N (1.0kg) is
applied to each terminal in axial direction.
The transducer should be subjected to a
vibration cycle of 10 to 55 Hz band of vibration
frequency for a period of 1 minute. Total peak
amplitude should be 1.5mm. The vibration test
should consist of 2 hours per axis in each axial
direction (X, Y, Z) for a total of 6 hours.

Evaluation Standard
95% of the surface of the lead
pads should be covered with
solder.
No interference in operation.
No damage or cutting off.
After the test, the part should
meet specifications without any
damage in appearance or
performance except for SPL. The
SPL should be within ±10dB
compared with the initial
measurement.
