STUDY OF LAYER STRUCTURES IN THE DEVICES OF INSTRUMENT ENGINEERING FOR INCREASING SAFETY IN THE PROCESS OF THEIR OPERATIONAL LIFETIME

Abstract: For micro-assemblies of the rectangular type representing the heterogeneous structure, the mathematical simulation of strain-stress state for their components was performed at external excess pressure testing. While constructing the mathematical model, the finite element method was used implemented in ANSYS package when one or several multilayer boards are mounted on any plane of the case. The numerical study of micro-assemblies strain-stress state was made and the critical recommendations were given regarding the determination of allowable pressure in the pressure testing taking into consideration the design and engineering particulars of the micro-assembly under design.
