In the semiconductor shortage market, more and more counterfeit chips began to circulate in the electronic field. This will bring quality risks to more electronic products and seriously damage the interests of manufacturers and users. San Xin is an industry slang. It usually refers to chips without original packaging. It will also be used to refer to chips eliminated due to quality problems in the assembly line and refurbished chips. Some second-hand refurbished chips can be used for new equipment, but the service life of consumer grade chips is about 5 years. If they are used after refurbishment, their service life and performance parameters will be greatly reduced. What is the quality of the "refurbished goods" in the chip? What are the common means of refurbishment? If you are interested in what this article will cover, read on. View >>

Nowadays, with the progress of science and technology, electronic manufacturing technology is increasingly developed, the degree of integration is higher and higher, there are more and more processes, the structure is more and more fine, and the manufacturing process is more and more complex. Complex factors will inevitably lead to hidden defects in the manufacturing process. As a competitive manufacturer of electronic products, it constantly ensures the high accuracy of its performance, We should also ensure the stability of its quality. Therefore, it is necessary to carry out relevant inspection, so why do we do aging test? View >>

With the development of electronic technology, the degree of integration of electronic products is higher and higher, the structure is more and more subtle, the process is more and more, and the manufacturing process is more and more complex, which will produce some latent defects in the manufacturing process. The high and low temperature alternating damp heat testing machine is applicable to the adaptability of electrical, electronic, instrumentation, automotive electrical appliances, electronic parts and materials to storage and use under high and low temperature environment. It is applicable to schools, factories, military industry, scientific research, and other units to detect the performance indexes of various electronic components under high and low temperature or damp heat environment. High and low temperature test is a necessary test item for product reliability. What are the factors affecting product reliability in high and low temperature test? In order to help you have an in-depth understanding, this paper will summarize the relevant knowledge of high and low temperature testing. View >>

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 >>

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.
