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 No interference in operation. 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. 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. Fax: 503.612.2381 www.cui.com 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. 20050 SW 112th Ave. Tualatin, OR 97062 Date: 9/19/2006 Part No: CMT-1603 Unit: mm Description: piezo audio transducer Page No: 4 of 6 Environment Test Item High temp. test Low temp. test Humidity test Temp. cycle test Test Condition After being placed in a chamber at +85°C for 240 hours.
