Temperature Conditions Storage Temperature Range -40C 8. ~ Operation Temperature Range +75C -20C ~ +60C Terminal Mechanical Strength Terminal mechanical strength to be no interference in operation after pulled the terminal with 1kg strength for 1 minute. 9. Reliability Test After any following tests, the sensitivity of the microphone to be within ±3dB of initial sensitivity after 3hours of conditioning at 20 . 9.1 Vibration Frequency1 : Amplitude : Change of Frequency : 2 hours in each of 3 axes 10Hz~55Hz 1.52mm 1 octave/min 9.2 Dry Heat／Cold +70C／-20C for 72 hours 9.3 Damp Heat 90%～95%RH,+40C for 240 hours 9.4 Temperature Cycles -20 (2h) (1h) 25 (2h) (1h) 70 (2h) (2h) × -20 10 cycles 9.5 Packing Drop Test Height：1m Procedure: 5 times from each of 3 axis’s 10. Soldering Condition 10.1 We use anti-static welding machine which can control soldering temperature automatically. 10.2 Soldering temperature should be controlled under 320C. 10.3 MIC shall be fixed on the metal block (heat sink), which has high radiation effects，and heat sink shall contact with MIC tightly. 10.4 Soldering time for each terminal shall be 1~2 sec. 10.5 Soldering pinhole shall be avoided. 10.6 MIC 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).
