First, the deepening understanding of faults promotes the innovation of reliability theory and methods. Reliability engineering is a discipline that fights product failures. Early reliability workers developed a set of system reliability engineering techniques based on the understanding of the external statistical regularity of faults. As the understanding of faults goes from the outside to the essence, people gradually realize that the core of reliability work is to master and utilize the fault mechanism. Therefore, based on the failure physics, the reliability technology based on fault physics is developed. Under the premise of clarifying the mechanism of product failure, formulate corresponding design, maintenance and safeguard measures.
Second, advances in basic materials, components, and PCBA processing techniques have contributed to the development of reliability engineering. The continuous improvement of product reliability is due to the continuous improvement of materials, components, components and manufacturing processes. With the deepening of basic materials research, people have continuously improved the research and verification methods for the failure mechanism of various materials. The failure mechanism of the material under different application conditions has been mastered before the application, and can be quantitatively analyzed based on the simulation model, which provides an accurate input for the reliability design work based on fault physics.
Finally, the development of product information and digital design technology provides new technical means for the research and engineering application of reliability technology. With the support of computer, network communication, digital simulation and other related technologies, developed countries in Europe and America took the lead in realizing the digitization of the whole process of equipment development, improving the quality, reliability and performance stability of equipment. Through years of exploration, especially with the implementation of the nationalization strategy driven by the national informatization and the rapid advancement of digital construction in the military industry, the research and application of digital design and manufacturing has entered a new stage, which creates favorable conditions for the innovation of reliability engineering technology and integrated innovation.
