Ascending time up to 150°C should be longer than 30 seconds. Heating conditions should be within 10 seconds at 230°C min. Peak temperature should be lower than 235°C and then be placed in natural conditions for 1 hour before being measured. 2) Soldering Iron Soldering iron of 270±5°C should be placed 0.5mm above the transducer electrode. Melting solder should be applied to electrode for 3±1 seconds and then be placed in natural conditions for 4 hours before being measured. For 10 seconds, the force of 9.8N (1.0kg) is applied to each terminal in axial direction. The buzzer should be subjected to a vibration cycle of 10 to 55 Hz for a period of 1 minute. Peak amplitude should be 1.55mm. The vibration test should consist of 2 hours to each of the 3 perpendicular directions. evaluation standard 95% of the lead pad surface must be covered with solder test condition After being placed in a chamber at +80°C for 240 hours. After being placed in a chamber at -40°C for 240 hours. After being placed in a chamber at +40°C and 90±5% relative humidity for 240 hours. The part shall be subjected to 5 cycles. One cycle will consist of: evaluation standard No interference in operation. No damage or cutting off. After the test, the part should meet specifications without any damage in appearance and performance, except SPL. SPL should be within ±10dB compared with the initial measurement. ENVIRONMENT TEST item high temp. test low temp. test humidity test temp. cycle test The buzzer 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. 20050 SW 112th Ave. Tualatin, Oregon 97062 phone 503.612.2300 fax 503.612.2383 page 4 of 5 date 09/04/2007 DESCRIPTION: piezo audio transducer PART NUMBER: CMT-1102 RELIABILITY TEST item operating (life test) test condition 1. Continuous life test: The part will be subjected to 48 hours of continuous operation at +65°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 buzzer 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.
