The mechanical characteristics of multi-layer printed circuit boards (MPCB) determine, basically, the reliability of the entire device as a whole. The article is devoted to the issues of identifying the possibilities of modeling the mechanical characteristics of multi-layer printed circuit boards using the means of engineering analysis (CREO), since the results of modeling influence the amount of changes introduced to the design of the product during its finalization. Of great importance is the accuracy of modeling, which in turn depends on the given boundary conditions. The influence of boundary conditions and concentrated mass on the vibrational characteristics of a printed circuit board is analyzed. A comparative modal analysis of MPCB with various points of fixation and distribution of the mass of the installed components was carried out.
