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 follows the reflow temperature

curve to test its reflow thermo stability.

Terminal Mechanical Strength

Lead pads shall be soldered onto the pc

board and the force of 9.8 N (1.0 kg) shall

be applied behind the part for 10 seconds.

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 is to be dropped from a height of

75 cm onto a 40 mm thick wooden board 3

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

Evaluation Standard

95% surface of lead pads must

be covered with fresh solder.

No in interference in operation.

No damage or cutting off.

After the test, the part shall meet

specifications without any

damage to the appearance and

the SPL should be within ±10

dBA of the initial SPL.
