中文摘要:
      目的 研究薄膜体声波滤波器的加速寿命评估技术,针对XXX1001型薄膜体声波滤波器进行可靠性寿命评估。方法 根据薄膜体声波滤波器设计、结构特点,针对XXX1001型薄膜体声波滤波器典型应用环境条件下的失效模式和失效机理分析,采用环境影响分析明确寿命表征指标和相应敏感应力,以此确定合适的加速寿命方法和加速模型。结合可靠性摸底试验确定的敏感应力极限和加速模型要求,设计加速寿命试验方案,利用阿伦尼斯模型对寿命表征指标等试验数据进行评估,得到该型薄膜体声波滤波器的可靠性寿命参数。结果 确定了滤波器的寿命表征指标(插入损耗)和敏感应力(温度),设计了加速寿命试验方案,试验实施后,根据试验数据评估出XXX1001型薄膜体声波滤波器在40 ℃工作时的平均寿命为117 803 h。结论 该技术程序较为简单、实施方便、样本少、成本低,可为类似滤波器的可靠性评估提供参考。其评估结果也可为XXX1001型薄膜体声波滤波器的设计改进和应用推广提供技术支撑。
英文摘要:
      Objective To study the accelerated life assessment technology for the film bulk acoustic filter and evaluate the reliability life for the XXX1001 film bulk acoustic filter. Methods According to the design and structural characteristics of the film bulk acoustic filter, the failure mode and failure mechanism of the XXX1001 film bulk acoustics filter under the typical application environmental conditions were analyzed, and the analysis of environmental impact was adopted to make clear the life characterization index and the corresponding sensitive stress, to determine the appropriate accelerated life method and the accel-erated model. In combination with the sensitivity stress limit and the requirement of accelerated model, the accelerated life test was designed and the reliability life parameter of this type of film bulk acoustics filter were obtained by evaluating the test data such as the life characterization index with the Arrhenius model. Results The life characterization index (insertion loss) and the sensitive stress (temperature) of the filter were obtained. The accelerated life test plan was designed. After testing, in combination with the test data, the average life of XXX1001 film bulk acoustic filter was evaluated to be 117 803 h when working in 40℃. Conclusion The technical procedure is simple, easy to implement, with few samples and low cost, which can provide a reference for the reliability evaluation of similar filters. The evaluation results can also provide technical support for the design improvement and application promotion for the XXX1001film bulk acoustic filter.
