Ascending time up to 245C should be longer than 55 seconds. Heating conditions should be within 20 to 40 seconds at 245C min. Peak temperature should be lower than 255C. The transducer should be measured after 1 hour in normal No interference in operation. conditions. 2) Soldering Iron A soldering iron of 2705C should be placed 0.5mm away from the electrode of the transducer. Melted solder should be applied to the electrode for 31 seconds. The transducer should be measured after 4 hours in normal conditions. For 10 seconds, the force of 9.8N (1.0kg) is applied to each terminal in axial direction. 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. Soldering Heat Resistance Terminal Mechanical Strength Vibration 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.

After being placed in a chamber at -40C for 240 hours. After being placed in a chamber at +40C and 905% relative humidity for 240 hours. The part shall be subjected to 5 cycles. One cycle will consist of: Evaluation Standard The transducer should be measured after being placed at +25C 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 Operating (Life Test) Test Condition 1. Continuous life test: The part will be subjected to 48 hours of continuous operation at +55C 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 2C) with rated voltage applied. Evaluation Standard The transducer will be measured after being placed at +25C 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.
