test condition
After being placed in a chamber at +120°C for 240 hours.
After being placed in a chamber at -40°C for 240 hours.
After being placed in a chamber at +40°C and 90 ±5% RH for
240 hours.
The part will be subjected to 5 cycles. One cycle will consist of:
test condition
Lead terminals are immersed in rosin for 5 seconds and then a
solder bath of +270 ±5°C for 2 ±0.5 seconds.
1) IR Reflow
2) Soldering Iron
For 10 seconds, the force of 9.8 N (1.0 kg) is applied to each
terminal in each axial direction.
The buzzer should be measured after a vibration amplitude of
1.55 mm with 10 ~ 55 Hz band of vibration frequency to each of
the 3 perpendicular directions for 2 hours.
Piezo assembly on the spot for each piece of wire, to exert the
level of tension, the rate of 20 mm/minute, may have to bear the
minimum of 200 g rally.
Pre-heating conditions of 150~200°C for 60~180 seconds.
Ascending time up to 250°C shall be longer than 55 seconds.
Heating conditions will be within 15 seconds at 245°C min.
Peak temperature will be lower than 250°C, then after being
placed in natural conditions for 1 hour, the transducer will be
measured.
Soldering iron of 270±5°C will be placed 0.5 mm above the
electrode of the transducer. Melting solder through the
soldering iron will be applied to electrode for 3±1 seconds.
Then, after being placed in natural conditions for 4 hours, the
transducer will be measured.

evaluation standard
95% min. of the surface of the lead
pads will be covered with solder.
No interference in operation.
No damage or cutting off
After the test, the part will meet
specifications without any damage in
appearance and performance except
SPL. The SPL should be within ±4dB
compared to the initial measurements;
higher than 81 dB.
The product which was tested cannot
be packed and delivered, it should be
abandoned.
evaluation standard
The buzzer will be measured after
being placed at +25°C for 4 hours.
The value of the oscillation frequency
/ current consumption should be
±10% compared to the initial
measurements. The SPL should
be within 4 dB compared to the
initial measurements. Higher than
81 dB.
