evaluation standard

After the test, the part will meet

specifications without any

damage in appearance except

SPL. After 4 hours at 25°C, SPL

should be within ±10% of the

initial measurements.

MECHANICAL CHARACTERISTICS

item

test condition

solderability

Lead terminals are immersed in solder bath

of 270 ±5°C for 3 ±1 seconds.

soldering heat resistance

The product should follow the reflow

temperature curve to test its reflow thermo

stability.

terminal mechanical strength

For 10 seconds, the force of 9.8N (1.0kg) is

applied to each terminal in axial direction.

vibration

The buzzer will be measured after applying

a vibration amplitude of 1.5 mm with 10 to

55 Hz band of vibration frequency to each of

the 3 perpendicular directions for 2 hours.

drop test

The part will be dropped from a height of

75 cm onto a 40 mm thick wooden board 3

times in 3 axes (X, Y, Z) for a total of 9 drops.

evaluation standard

95% of the surface of the lead

pads will be wet 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 the

SPL should be within ±10% of the

i initial measurements.
