2 / 4 page MODEL: ST-1411 PRODUCT: Electro Magnetic Buzzer EDITION: A/2016 RELIABILITY TEST item test conditions evaluation standard operating life test CONTINUOUS LIFE TEST The part will be subjected to 72 hours of con- tinuous operation at +60oC with 3.6V, 3200Hz applied After the test the part will meet specifications without any degradation in appearance and performance except SPL, after 4 hours at +25oC. The SPL would be in ±10dBA compared with initial one. INTERMITTENT LIFE TEST A duty cycle of 1 minute on, 1 minutes off, a minimum of 10,000 times at room temp. (+25±10oC)with 3.6V,3200Hz applied. TEST CONDITION Standard Test Condition : a)Temperature: +5~+35℃ b)Humidity:45~85% c)Pressure: 860~1060mbar MECHANICAL CHARACTERISTICS item test condition evaluation standard solderability Lead terminals are immersed in solder bath of +270±5oC for 3±1 second 90% min. lead terminals will be wet with solder No interference in operation. soldering heat resistance The product followed the reflow profile to test its reflow thermo-stability. terminal mechanical strength Lead pads will be soldered on the pc board, and the force 9.8N(1.0Kg) will be applied behind the part for 10 seconds. No damage and cutting off vibration The part will be subjected to a vibration cycle of 10Hz to 55Hz to 10Hz in a period of 1 minute. Total peak amplitude will be 1.52mm(9.3G). The vibration test will consist of 2 hours per axis in each three axes (X,Y, Z). Total 6 hours. After the test the part will meet specifications without any damage in appearance and per- formance except SPL. SPL would be in ±10dBA compared with initial one. drop test The part only shall be dropped from a height of 75cm onto a 40mm thick wooden board 3 times in 3 axes (X,Y, Z). Total of 9 times.
