Modeling and Experimental Research of Vibration N Properties of A Multi-Layer Printed Circuit Board

Abstract

Radio-electronic modules of modern devices are an assembly of a large number of a printed circuit board (PCBs), placed in a secure mechanical case. Several heavy electronic components mounted on the printed circuit board (PCB). In the process of operation, the unit Many to various types of loads, such as vibrations and shocks. The main contributions of this work are to reduce the designing time and, thereby, to increase efficiency, computer simulation (modeling) widely used. Accuracy of the engineering machine analysis is one of the cornerstone tasks. The article contains information on the modeling of a large-size PCB by simulation in the Creo Elements/Pro 5.0 Environment, with a comparison of the obtained data with the results of the testing of PCBs on the vibration stand. There is proposed the method of the preliminary analysis of PCBs on mechanical characteristics, before their designing.
