Dynamic response of PC boards: Some useful analysis guidelines

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.
