Приведены результаты исследования влияния вибраций на материал электронных плат. Исследования проводились на вибрационном стенде с установленным на нем каскадам из плат навигационных приборов. Эксперименты проводились в колебательном диапазоне 0,5–10 Гц; диапазоне напряжений 0–3 В; разрешенном температурном диапазоне 0 – +45 °C. Для определения координат локализованных источников акустической эмиссии применен метод амплитуд. Установлено, что изначально напряжение и относительная деформация возрастают, а далее снижаются. Уменьшение показателей роста механического напряжения dσ/dε происходит вследствие разрушения структуры материала. Во время эксперимента использовались получающий сигнал пьезопреобразователь на основе керамики ЦТС-19 и волновод, который находился в акустическом контакте с прототипом. Установлено, что при вибрации образуются микродефекты за счет разрыва микрообъемов материала плат.

The aim of this work is to investigate the influence of vibrations on the material of the board. For that purpose a cascade of navigation devices boards was installed on the vibrational stand. Experiments were performed in the 0,5–10 Hz vibrational diapason range; 0–3 V voltage range; 0 – +45 °C allowed temperature range. Amplitude method was applied to determine the coordinates of localized sources of acoustic emission. The results indicate the initial increase in tension and relative deformation and further their decrement. Growth rate reduction of mechanical stress dσ/dε is due to destruction of material structure. The receiving piezo converter based on ЦТС-19 ceramics and a waveguide that was in acoustic contact with the sample were used during experiments. The acquired experimental data on acoustic emission reflect the formation of microdefects and the instability of mechanical tension, its avalanche and explosive tendency in the material when the microvolumes of material are torn.
