The estimation of the mechanical reliability of the Printed Circuit Board (PCB) in an electronic system is considered to be an important part of the overall reliability of the system. The vibration often plays the key cause of invalidation and component failures. Since it is known that such vibration factors can induce various failures, an understanding of their dynamic response is warranted. Random vibration test is specified for acceptance tests, screening tests and qualification tests as it more closely represents the true environment in which electronic system must operate. In order to achieve a good vibration analysis, it is first necessary to efficiently and accurately understand the dynamic behavior of the system when subjected to specific environment like random vibration. Once the methodology is built, it can be applied for analyzing various systems with greater confidence in estimating their dynamic response.
