Background. In modern digital devices, the issue of a comprehensive assessment of transmission lines, which are copper tracks on a printed circuit board and associated structural elements, becomes more and more important. Predicting their behavior, assessing the electromagnetic waves generated by useful and parasitic signals propagating in them and their mutual influence on each other through modeling plays an essential role in assessing the performance of a product. Materials and methods. Geometric parameters of copper tracks, characteristics of electronic components placed on the board and the density of their mounting with a constant increase in operating frequencies and a decrease in supply voltages can significantly affect the electromagnetic environment, the parameters of transmitted pulses and the operation of internal microcircuit nodes, leading to instant or delayed, periodic in time failures different types of criticality. Results. The paper shows that in order to minimize possible risks associated with various physical phenomena and the resulting parasitic parameters of the printed circuit board materials, it is necessary to simulate its operation, taking into account the possible parameters of the materials used and their effect on at least the most critical areas – printed wiring, places installation of microcircuits and other radioelements. The S-parameters of the selected section of the printed circuit board are determined, in particular, the S11 parameter, which is the main parameter when assessing possible multiple reflections in a group of copper paths in the band up to 10 GHz. Conclusions. The performed studies allow us to exclude, based on the results of modeling, the factors caused by the unsuccessful geometry of copper routes and the location of electronic components that negatively affect the parameters of the transmitted signals.
