Part No: CMT-1603 Description: piezo audio transducer Date: 9/19/2006 Unit: mm Page No: 3 of 6 Mechanical Characteristics Item Test Condition Solderability Lead terminals are immersed in rosin for 5 seconds and then immersed in solder bath of 270 ±5°C for 2 ±0.5 seconds. Soldering Heat Resistance 1) IR Reflow Pre-heating conditions should be 150~200°C for 60 to 180 seconds. Ascending time up to 245°C should be longer than 55 seconds. Heating conditions should be within 20 to 40 seconds at 245°C min. Peak temperature should be lower than 255°C. The transducer should be measured after 1 hour in normal conditions. 2) Soldering Iron A soldering iron of 270±5°C should be placed 0.5mm away from the electrode of the transducer. Melted solder should be applied to the electrode for 3±1 seconds. The transducer should be measured after 4 hours in normal conditions. Terminal Mechanical Strength For 10 seconds, the force of 9.8N (1.0kg) is applied to each terminal in axial direction. Vibration The transducer should be subjected to a vibration cycle of 10 to 55 Hz band of vibration frequency for a period of 1 minute. Total peak amplitude should be 1.5mm. The vibration test should consist of 2 hours per axis in each axial direction (X, Y, Z) for a total of 6 hours. Evaluation Standard 95% of the surface of the lead pads should be covered with solder. No interference in operation. No damage or cutting off. After the test, the part should meet specifications without any damage in appearance or performance except for SPL. The SPL should be within ±10dB compared with the initial measurement.

Part No: CMT-1603 Description: piezo audio transducer Date: 9/19/2006 Unit: mm Page No: 4 of 6 Environment Test Item Test Condition High temp. test After being placed in a chamber at +85°C for 240 hours. Low temp. test After being placed in a chamber at -40°C for 240 hours. Humidity test After being placed in a chamber at +40°C and 90±5% relative humidity for 240 hours. Temp. cycle test The part shall be subjected to 5 cycles. One cycle will consist of: Evaluation Standard The transducer should be measured after being placed at +25°C for 4 hours. The value of the oscillation frequency/current consumption should be ±10% compared to the initial measurements. The SPL should be within ±10dB compared to the initial measurements. Reliability Test Item Test Condition Operating (Life Test) 1. Continuous life test: The part will be subjected to 48 hours of continuous operation at +55°C with rated voltage applied. 2. Intermittent life test: A duty cycle of 1 minute on, 1 minute off, a minimum of 5,000 times at room temp (+25 ±2°C) with rated voltage applied. Evaluation Standard The transducer will be measured after being placed at +25°C for 4 hours. The value of the oscillation frequency/current consumption should be ±10% compared to the initial measurements. The SPL should be within ±10dB compared to the initial measurements. Test Conditions Standard Test Condition a) Tempurature: +5 ~ +35°C b) Humidity: 45 - 85% c) Pressure: 860-1060 mbar Judgement Test Condition a) Tempurature: +25 ±2°C b) Humidity: 60 - 70% c) Pressure: 860-1060 mbar
