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?

Now, with the progress of society, there are more and more electronic products on the market, such as watches, smart phones, telephones, televisions and so on. After these electronic products are developed, some companies flow directly to the market without testing. In fact, this is unqualified. Any company must carry out various tests on its products to confirm whether they meet the standards. You can only go online if you meet the standards. For this reason, many friends will pay great attention to the quality inspection of electronic products? What are the inspection standards for electronic products? Next, we will answer them one by one. View >>

Power management chip is widely used in household appliances, mobile phones and tablets, industrial control equipment and other fields. It is the power supply heart of all electronic equipment. It controls the pulse of electronic equipment - electric energy, and is responsible for the functions of electric energy conversion, distribution and detection. Once it fails, it will directly cause the electronic equipment to stop working or even damage. It is a key device in electronic equipment. If the power chip is damaged in the circuit, it will cause the electronic equipment to stop working. For the detection and identification of IC electronics, let's understand the quality measurement method of the power chip in the power circuit. View >>
