8. Terminal Mechanical Strength
Terminal should be no interference in operation after pulled the terminal with 1kg for 1 minute.
9. Reliability Test
After each of following test, the sensitivity of the microphone should be within ±3dB of initial sensitivity after
3hours of conditioning at 20℃.
1. Vibration Test
Frequency : 10Hz~55Hz
Amplitude : 1.52mm
Change of Frequency : 1 octave/min
2 hours in each of axes
2. High Temperature Test
+70℃ for 72 hours.
3. Low Temperature Test
-20℃ for
72 hours.
4. Humidity Test
90%～95%RH,+40℃ for 240 hours.

Procedure: 5 times from each of axes
10. Soldering Condition
1.
We suggest using anti-static welding machine which can control soldering temperature automatically.
2.
Soldering temperature should be controlled under 320℃ and
sec..
3.
Microphone should be fixed on the metal block (heat sink), which has high radiation effects, and heat sink
shall contact with MIC tightly.
4.
Microphone may easily be destroyed by the static electricity and the countermeasure for eliminating the static
electricity shall be executed (worktable and human body shall be ground connection).
soldering time for each terminal should be 1~2
