Generalized problem of vibration reduction of elements of electronic engineering structures, identified an unresolved problem of determining their own oscillation frequencies. Methods and tools for experimental determination of the natural oscillation frequency of printed circuit boards and micromodules using direct and inverse piezoelectric effects have been developed, as well as a developed and modified Hook-Cool method. It is experimentally determined that the dense spectrum of natural oscillation frequencies of REA products depends on the design features of the micromodules installed on them. It is established that the amplitude and form of oscillations of micromodules are influenced by their design and technological execution. The experimental data obtained indicate the need to take into account the location of the motherboards, as well as the micromodules located on them on the surface of the device, since the level of their amplitude of oscillations depends on it. Experimental studies of the effectiveness of the use of the cubic fixture.
