| 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. |
