摘要
A method for assessing reliability of an electronic component under downhole vibration conditions include designing a set of vibration test conditions and conduct failure analysis. The vibration test conditions include the natural vibration frequency, the overstress limit of the test vehicle, and the step stress profile for testing the test vehicle. The failure analysis of the failed electronic component includes the step of measuring an electrical resistance of the failed electronic component without a vibration load. When the electrical resistance of the failed electronic component remains large, the failed electronic component is cross-sectioned. Finally, the cross-sectioned electronic component is examined to identify a failure mode.
