Failure analysis is a new developing subject. The common technical means of failure analysis include appearance inspection, nondestructive testing, thermal analysis, electrical performance testing, dyeing and penetrant testing. It usually simulates and reproduces the failure phenomenon according to the failure mode and phenomenon, finds out the failure cause and finds out the failure mechanism through analysis and verification. It has important practical significance for improving product quality, technology development, process improvement, product maintenance and arbitration of failure accidents. View >>

Chip is the most basic semiconductor material for IC production. The quality of chip determines the quality of IC finished products. The chip size detection system detects the position and size of each part of the chip. Before processing the chip, it is very important to strictly detect the appearance and size of the chip, which is conducive to the subsequent processing and improve the chip processing efficiency. After the chip size detection system is simply set, it can automatically detect and calculate. In case of abnormality, it can prompt the alarm or control the machine to stop. Ng signal can be output after detecting the workpiece that does not meet the requirements. View >>

Electrical appliances operate through the movement of current, while capacitors achieve the effect of capacitance through the voltage of electrical appliances. This type of products often encounter a fatal problem in the process of use, that is, short circuit. Once the product is short circuited, it is nothing more than the failure or damage of the internal capacitance, Therefore, it is very important to analyze and solve the causes of short circuit.

PCBA is a system composed of PCB and various electronic components. The main material of PCB is the composite of glass fiber and epoxy resin, which is divided into single panel, double-sided board and multilayer board. As we all know, product failure will cause serious economic losses and quality impact. However, PCB failure modes are diverse, and the root causes of failure are also different, such as corrosion failure of PTH hole copper, open circuit failure caused by crack at the bottom of HDI blind hole, layered plate failure, hole ring crack of ENIG product and short circuit fire of PCB, etc. View >>

With the development of science and technology, especially the upgrading of electronic technology, the quality requirements of components used in electronic equipment are higher and higher. With the wide use of semiconductor devices, their life is degraded and eventually lead to failure. A large part of electronic components work in extreme temperature and harsh environment, resulting in failure to work normally, and a large part of components stop in laboratories and wafer factories during R & D. In addition to improper use, surge and electrostatic breakdown, which are all the reasons for the shortening of the service life of semiconductor devices, some devices running normally are also damaged and the components are degraded.

With the rapid rise of domestic testing institutions industry, the development trend of testing institutions has also become a topic of discussion. The government will accelerate the transformation of functions, and a large number of technical work will be undertaken by third-party inspection and testing institutions. The inspection and testing market will enter the fast lane of development by purchasing services and accepting results. Testing the products that have been produced and processed is a necessary procedure for all manufacturers. In this process, the level of cooperative testing institutions should not be careless. Institutions with high testing level and good testing quality can dutifully provide detailed testing results to avoid inaccurate product testing by informal testing institutions, So specifically, what are the precautions for selecting a formal third-party testing organization?
