Institutional Profile

The Institute of Electrical and Electronic Reliability was established in 2001, relying on the State Key Discipline of Electric Motors and Electrical Appliances, the Key Laboratory of Electronic Component Reliability and Quality Consistency of the Ministry of Education, the National Ministry Mechanic and Electronic Component Professional Technical Public Service Platform, the Ministry of Industry and Information Technology's Industrial Technology Foundation Public Service Platform, and the Key Laboratory for Electrical and Electronic Reliability Technology of Heilongjiang Province. It is the only professional research institute in China that is dedicated to space electrical equipment. The institute has been recognized by the China National Accreditation Service for Conformity Assessment (CNAS) and the China Metrology Accreditation (CMA). It has gathered a high-level research team consisting of 18 teachers, more than 70 doctoral and master's students, and more than 70 engineers. The team includes one national-level high-level talent, two national-level young talents, and one IET Fellow. The institute has completed or is conducting more than 100 research projects, including national ministry pre-research projects, the National Natural Science Foundation of China, the National 863 Program, and research on quality engineering. The institute has published more than 800 academic papers (including over 400 collected in SCI and EI indices) and has obtained more than 157 authorized invention patents. It has won one second prize for national scientific and technological progress, two first prizes for scientific and technological progress of ministries and commissions, and more than 10 provincial and ministerial scientific and technological progress awards. The institute has established 17 school-enterprise joint research and development centers with industry-leading companies such as Xiamen Hongfa (the world’s largest relay enterprise) and AVIC Optoelectronics (the largest connector enterprise in China) to solve the industry's common technical problems and make outstanding contributions to China’s quality engineering.

Research Direction

The institute focuses on serving national major needs and the main battlefield of the national economy, with a focus on aerospace. For 30 years, the institute has been committed to solving the “neck-breaking” key common technical problems of the reliability and quality consistency of electrical and electronic products. Its main research directions include:

(1) High-reliability electrical equipment

(2) Electronic equipment reliability

(3) Electromagnetic and ultrasonic non-destructive testing.

Significant Achievements

1. Key Technologies and Applications for Aerospace Electrical Reliability and Quality Consistency

We have successfully introduced the forward design theory and method for aerospace electrical mechanisms, resulting in the development of a series of innovative mechanisms that possess resistance to burning and vibrations, as well as low power consumption for electromagnetic and spring devices. This breakthrough has ended our long-standing reliance on foreign products. Additionally, we have significantly increased the overload capacity of aerospace electrical devices, achieving an 8-times increase, which surpasses the highest capacity in the United States, which is 5 times. Moreover, we have overcome the major technical challenges associated with the multi-objective high-reliability design of aerospace electrical devices. This accomplishment has resolved the problem of mutual constraint and complex optimization. Furthermore, we have prolonged the lifespan of aerospace electrical devices from 20,000 to 100,000 cycles. Additionally, we have improved the resistance to environmental reliability up to 30g10~3000Hz, exceeding the highest level achieved in the United States, which is 30g10~2500Hz. Our team has also developed a new technology that ensures consistent quality throughout the entire lifecycle of aerospace electrical devices. This innovation addresses the significant technical challenge of poor-quality consistency caused by uncertainties from various sources. As a result, we have enhanced the consistency of the electrical device lifespan by 55% and reduced the torque standard deviation by 70% (28% reduction in Japan). The successful implementation of our research and technology has allowed us to achieve independent control over aerospace electrical devices in 58 major aerospace projects. This significant milestone has greatly increased the localization rate of aerospace electrical devices within the China Aerospace Science and Technology Corporation and Shanghai Academy of Spaceflight Technology, leading to a notable decrease in quality issues. As a recognition of our achievements, we were honored to receive the first prize of the 2021 National Science and Technology Progress Award from government departments.

2. Automatic Detection Technology for Sealed Electronic Components and Residual Debris in Electronic Equipment

We have made significant advancements in the field of detecting and identifying residual debris particles. Firstly, we have developed a dynamic model for the collision of these particles and proposed optimal test conditions for their detection. This addresses a major technical challenge where existing military standards were not fully utilizing their detection capabilities. Additionally, we have established a coupling model for detecting signals of residual debris and proposed automatic detection and material identification methods. This has enabled us to effectively detect debris weighing 0.1μg with a detection accuracy higher than 95% and material identification accuracy higher than 90%. In terms of technology and equipment, we have developed the first set of six automatic detection systems for residual debris in China. These systems have surpassed similar international products in terms of detection sensitivity, accuracy, and material identification capability. This achievement has broken the monopoly of foreign technologies and equipment in this field. In recognition of our accomplishments, we were awarded the second prize of the 2014 National Science and Technology Progress Award. Since 2014, we have continued to advance our capabilities. We established a sensitivity measurement system for residual debris acoustic emission sensors in China and developed the first large thrust vibration table for residual debris testing. Additionally, we overcame key technologies such as robot vision-guided automatic detection, achieving high-precision digitalization and intelligence in residual debris detection. As a result, we have become the sole producer of residual debris detection equipment with fully independent intellectual property rights in China, commanding a market share of over 60%. Our equipment has been successfully deployed in 152 aerospace major models and support units, including prestigious organizations like the Kunming Institute of Physics and China Hexi Chemical Machinery Company. This has ensured rapid positioning and material identification of residual debris, guaranteeing the quality of the assembly process and improving the reliability and safety of aerospace models and major equipment.
