First, the characteristics of modern electronic products

660-088884-002 Electronic products refer to the use of electronic technology to manufacture electrical energy based work related products, including power/electrical equipment and microelectronics instruments, equipment and systems. Electronic products are widely used in national defense, various departments of the national economy and various fields of people’s life.

660-088884-002 Early electronic products are mainly manufactured on the basis of electronic tube components, the function is relatively simple, the circuit and structure are not complex, and the manufacturing is not difficult. With the development of production and science and technology, the application of new processes and new materials, as well as the development and promotion of ultra-miniaturized components and medium – and large-scale integrated circuits, electronic products have undergone great changes in circuit and structure, and the emergence of miniaturized, ultra-miniaturized and miniaturized structures. Some traditional design methods are gradually replaced by new technologies such as electromechanical combination and photoelectric combination.

With the continuous enhancement of product performance, the continuous improvement of complexity and the continuous expansion of application fields, the reliability requirements of electronic products are increasing day by day, especially in the fields of military, communications, life medical and aviation/aerospace, the reliability of electronic products has become an important indicator to measure the performance of electronic products.

Compared with earlier electronic products, modern electronic products have the following characteristics.

(1) The product composition is more complex and the assembly density is greater

660-088884-002 Early electronic products are usually built by a small number of tubes and discrete components through simple connections, and have a single function. Modern electronic products usually have a variety of functions, product composition is more complex, the number of components, parts, while the volume and quality of the product is smaller, so the assembly density is greater. In particular, the emergence of ultra-large scale integrated circuits and various functional modules derived from them has greatly increased the assembly density of electronic products compared with the past.

(2) The equipment is widely used and the working environment is complex

660-088884-002 With the continuous expansion of applications, the range of working environments that electronic products need to adapt to is constantly expanding. Modern electronic products often have to work in harsh and demanding environments, such as geological drilling, offshore operations, Antarctic research, deep space exploration, etc. At this time, the product needs to withstand high temperature, low temperature and huge temperature difference, high humidity and low pressure, strong shock and vibration, external electromagnetic interference and cosmic ray radiation. These will have an impact on the normal work of electronic products.

(3) The equipment has high reliability requirements and long life

Early electronic products because of the simple structure, single function, the number of components used is small, often not easy to use problems, and even if there is occasional failure, it is relatively easy to repair. The complexity and precision of modern electronic products are higher, the number of components is more, if there is a failure, the difficulty and cost of maintenance will be greatly increased, so it requires higher reliability and long enough working life, and electronic products with low reliability will lose their use value. In order to obtain high-reliability electronic products, not only the quality of the components used is required to be higher, but also greater efforts should be made in circuit design and structural design.
