The printed circuit board (PCB) plays a vital role in modern electrical equipment and its reliability will affect electrics greatly. In order to study the vibration characteristics of the PCB, to guarantee its reliability, the finite element model of the PCB is established in ANSYS for the theory of modal analysis. Then, use the modal parameter identification technology to experiment modal analysis. The theoretical and experimental results are basically consistent. Under the premise of the correct model, quantitative analysis of the impact of a PCB thickness to its natural frequency is made in ANSYS. The research results show that the natural frequency of the PCB increases with the increase of the thickness, and the higher order leads to the faster growth, which will provide a reference for the PCB designing.
