Ways to improve strength reliability of electronics elements and systems

On the ground of the accumulated experience in the study and elimination of strength defects of electronic items or their failures due to mechanical effects, the paper analyses the problems of mechanical strength when designing, manufacturing and testing these items, including power electronics. Here are presented theoretical and experimental investigation of static and dynamic strength of typical components: resistors, capacitors, microcircuits of printed circuit board and diodes of micromodules in operating conditions, offered non-destructive methods for controlling, diagnosing and forecasting the strength by means of acoustic emission phenomenon.
