Parametric Optimization of Double-Sided Printed Circuit Board With Triple Modal Reservation Accounting Failures

Modal reservation (MR) allows both increasing the circuit reliability and implementing the effect of modal filtering. The paper presents the study of a printed circuit board (PCB) with MR with the reference conductor in the form of side polygons. The structure is analyzed by quasi-static simulation, and the minimization of the maximum ultra-wideband pulse amplitudes at the far end of the structure after failures is first estimated. Using the heuristic search, the parameters for the PCB structure before and after failures are obtained. It is shown that, before failures, the maximum amplitude (Umax) does not significantly change under the condition of matching and at fixed values of loads. However, after failures, the Umax changes. For this structure, with increasing delay differences between pulses, Umax after failure 3 increased. It is shown that with obtained values of the geometric parameters, amplitudes of decomposition pulses change differently before and after failures. A prototype of the PCB was designed based on this study
