During operation, the electronic device is affected by various external destabilizing factors: electromagnetic, mechanical, thermal. The reliability of the device in operating conditions is, as a rule, its defining characteristic. Statistical analysis shows that the number of failures caused by mechanical and thermal factors is in the range of 65-85%. Therefore, reducing the impact of these factors on electronic equipment is necessary to achieve the required reliability indicators. Structural and constructive modules (SCM) are the main component of electronic equipment. Already at the stage of designing the device, it is necessary to make such technical decisions that will make it possible to achieve the highest indicators of its reliability in operating conditions. The modern level of computing devices (personal computers - PCs) allows you to confirm the correctness of such decisions with the help of simulation modeling, identify possible problems, and avoid the most significant design flaws. But for this, it is necessary to create object-oriented software products - automated design systems (CAD) that make it possible to obtain quantitative indicators of the functional characteristics of the designed device at the design stage. To improve the quality of modeling, it is necessary to take into account a large number of various factors in the corresponding mathematical models, that is, the improvement of such models is a priority direction. Since the electronic device usually includes a large number of elements of the electronic structure, taking into account various parameters, model constants and functional indicators of each of them is a very Product Description popup.authors Nikitchuk Artem V. popup.nrat_date 2024-10-01 Close
