Abstract :
The dynamic behavior of printed circuit (PC) boards plays an important role in the reliability of a package. This paper is concerned with four issues that are important in estimating the dynamic response of PC boards, namely, limitations of estimates based on the first vibration mode, the importance of geometric nonlinearities, the influence of a component location on the modal mass distribution and the relative importance of errors in the mass and stiffness estimates of a board component
