Failure analysis is a developing emerging discipline, which has been popularized from military industry to ordinary enterprises in recent years. It is generally an activity to simulate and reproduce the failure phenomenon, find out the cause of failure and dig out the failure mechanism according to the failure mode and phenomenon through analysis and verification. It has strong practical significance in improving product quality, technology development and improvement, product repair and arbitration of failure accidents. The rapid development of electronic component technology and the improvement of reliability have laid the foundation of modern electronic equipment. The fundamental task of component reliability is to improve the reliability of components. View >>

Electronic information technology is the core of today's new technological revolution, and electronic components are the basis for the development of electronic information technology. Understanding the factors causing component failure in order to improve reliability is a necessary guarantee for the application of electronic information technology. The main failure modes of electronic components include but are not limited to open circuit, short circuit, burning, explosion, electric leakage, function failure, electrical parameter drift, unstable failure, etc. In order to promote the further development of electronic information technology, it is necessary to improve the reliability of electronic components, so we must understand the failure mechanism, mode and analysis technology of electronic components.

Before the global chip shortage, the problem of "fake chips" existed all the time, but people didn't pay too much attention. In fact, this is not the first time that a large number of counterfeit products have been triggered by the interruption of the chip supply chain. Recently, some media reported that there are problems such as fake chips and refurbished chips in China's largest electronic market. The reason is that there is a strong demand for chips in China. Some unscrupulous businesses use this speculation to harm manufacturers and consumers, which highlights the urgent demand for chips in the domestic market. View >>

As an upstream product of the electronic information industry chain, electronic components are the basis for the development of communication, computer and network, digital audio and video and other systems and terminal products. Whether the electronic components work reliably determines the normal operation of electronic equipment. The appearance defect detection of electronic components is a very key link. Because such products are generally small and have high requirements for quality, it is difficult to pass the manual mass detection. It is necessary to use the visual detection equipment of electronic components for automatic appearance defect detection. View >>

The appearance of electronic products is one of the important factors to control the quality. With the rapid development of information technology, the demand for electronic components in China is gradually increasing. At present, electronic components are also gradually developing towards thin, intelligent, integrated and miniaturized. Whether there are defects or not not not not only affects the beauty of the product, but also directly affects the use and subsequent processing of the product itself, bringing significant economic losses to the enterprise.

According to the RoHS regulations issued by the European Union, the limits of six hazardous substances in electronic components, lead, mercury, cadmium, hexavalent chromium, polybrominated diphenyl ethers and polybrominated biphenyls, shall not exceed 1000ppm, of which the limit of cadmium is 100ppm. Those meeting these requirements are environmental protection products. The ROHS test report issued by the third testing organization is required for evaluation. RoHS is a mandatory standard formulated by EU law, with the full name of restriction of hazardous substances. This standard was officially implemented on July 1, 2006. It is mainly used to standardize the material and process standards of electronic and electrical products to make them more in line with the requirements of human health and environmental protection View >>

With the rapid development of science, technology, economy and trade, the development and utilization of natural resources, the environment encountered in the storage, transportation and use of various products is becoming more and more complex and harsh. From tropical zone to cold zone, from plain to plateau, from ocean to space and so on, both users and producers are concerned about the performance, reliability and safety of products in the above environment, so as to ensure that products can work satisfactorily. Therefore, environmental tests must be carried out. View >>

The national military series standards for quality management and quality assurance (GJB / z9001-9004-96) issued in 1996 is prepared according to the requirements of the regulations on the quality management of military products (hereinafter referred to as the regulations) and on the basis of the corresponding national standards for quality management and quality assurance (GB / t19001-gb / t19004-1994). China's military standards are mainly divided into three categories: military specifications, military standards and guiding technical documents. View >>

Military standards are military standards. For example, the full name of China's military standards is the national military standards of the people's Republic of China, which means that the equipment meets the standards and specifications of military specifications or military purposes. It is similar to the national standard in nature and is a basis for testing whether a certain product is qualified or meets the fixed specification requirements. The release and implementation of military series standards have promoted the rapid development of the construction of military product quality management system and the improvement of military product quality and reliability. In order to help you have an in-depth understanding, this paper will summarize the relevant knowledge of military product environmental test and reliability test project standards.

Mil-std-810 is a series of environmental test standards designed by the U.S. Department of Defense (DoD) for military products to test the reliability and durability of military products in a certain life cycle under a number of simulated harsh environments. This standard is also often used in general consumer electronics products to ensure that they can withstand the test in extreme environments and maintain the same performance. American Standard mil-std-810g certification test American Standard mil-std-810g does not refer to a test item. China's military equipment environmental test standard GJB150A is adapted based on American Standard mil-std-810g. It covers reliability tests such as climate environment and mechanical environment, compared with other common electronic equipment environmental tests View >>
