Reliability Tests Doc: MB3015USB-4 Note: After any of the following tests performed, the sensitivity of the microphone unit shall not deviate more than ±3dB from its initial value. The microphone shall maintain its initial operation and appearance. Measurements for tests with thermal requirements are to be done after 2hrs of condistioning at 20°C. The microphone to have no interferance in operation after vibrations, 10Hz to 55Hz for 1 minute full amplitude 1.52mm, for 2 hours at three axises. The microphone unit must operate when dropped three times once on each axis from a height of 1m onto a metal plate. High The microphone unit must operate within its sensitivity specifications after subjected to the following conditions: +85°C for 200 hrs, and exposed to room temperature for 2 hrs. The microphone unit must operate within its sensitivity specifications after subjected to the following conditions: -40°C for 200 hrs, and exposed to room temperature for 2 hrs. Vibration Test Drop Test Temperature Test Low Humidity Test Temperature Cycle Test +60°C at 95%RH for 200 hrs After exposure at -40°C for 45 minutes, at +85°C for 45 minutes, 27 cycles. (The measurements to be done after 2hrs of conditioning at +20°C.)transition time : 15 min. IV. Dimensional Drawing V.
