Solderability
Lead Wire Pull Strength
Vibration
The piezo electric diaphragm should be clamped at a node point (as shown in the following figure) to be free from any
mechanical stress. Measure its resonant frequency and resonant impedance by using a vector impedance analyzer or
equivalent.
When the input frequency is swept within 100 Hz to 5 KHz, the resonant frequency is defined as the frequency where
the impedance shows minimum value. This impedance should be the resonant impedance.
The electrostatic capacitance should be measured at 120 Hz by using an L.C.R. meter (ex. HP4194A(H.P.)) or
impedance mentioned above.
equivalent. The part should be clamped in the same way as the measurement or resonant frequency / resonant

Test Condition
Stripped wires of lead wires are immersed in
rosin for 5 seconds and then immersed in
solder bath of 270 ±5°C for 3 ±0.5 seconds.
The horizontal force of 3.0N (0.306kg) should
be applied to the double lead wire for 30 sec.
The diaphragm should 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.

Evaluation Standard
90% min. of the stripped wires
will be wet with solder.
(Except the edge of the terminal)
No damage or cutting off.
The value of the resonant
frequency should be ±10% of the
initial measurements.
Electrostatic capacitance should
be ±20% compared with the initial
measurement. The resonant
impedance should be 2000Ω
