Methods for ensuring the reliability of electronic equipment design during design

The article is devoted to a comprehensive review of methods for ensuring the reliability of radioelectronic equipment (REA) structures during design, taking into account the specifics of mechanical loads and operating conditions. The main attention is paid to the calculation and modeling procedures necessary to predict the reaction of the structure to external influences. The most widespread types of loads are analyzed: static, variable, contact, and fatigue loads, and strategies for improving the strength characteristics of structures are proposed, such as the introduction of stiffeners, optimizing the placement of fasteners, and selecting materials with high elasticity and strength. A significant place is devoted to the issues of ensuring the thermal regime of the REA, including methods for calculating the required cooling intensity and rules for organizing the air flow inside the structure. The most important factors affecting the life cycle of electronic equipment, such as overheating and unacceptable wear of components due to heating, are considered. The problems of electromagnetic shielding necessary to protect equipment from external interference and its own internal noise are highlighted separately. Recommendations for the creation of effective shielding shells are given, and the technology for the correct connection of wires and cables, which prevents the penetration of extraneous signals into the structure, is discussed. Thus, the article will become a valuable guide for design engineers seeking to create reliable and durable designs of radio electronic equipment that can function successfully even in extreme operating conditions.
