Why should the product be tested for reliability? Why should enterprises conduct reliability testing on products? What is the significance of reliability testing? The so-called reliability is the ability of the product to complete the specified functions under the specified conditions and within the specified time. In the process of design and application, the product is constantly affected by its own and external climatic environment and mechanical environment, but still needs to be able to work normally. This requires the use of test equipment to verify it. This verification is basically divided into three parts: R & D test, trial production test and mass production sampling inspection. In short, reliability refers to the ability to complete specified functions within specified time and under specified conditions. View >>

Generally speaking, the failure of integrated circuits is inevitable in the process of development, production and use. With the continuous improvement of people's requirements for product quality and reliability, failure analysis is becoming more and more important. Chip failure analysis can help integrated circuit designers find design defects, mismatching of process parameters or improper design and operation. How to accurately judge the quality of the power IC chip in the circuit is an important work for the maintenance of TV, audio and video equipment. If the judgment is not accurate, it will not only cost a lot of energy, but also the key is that the integrated circuit fault still exists. Therefore, to correctly judge the integrated circuit is a compulsory course for every maintenance personnel. View >>

Reliability test is an activity to evaluate the functional reliability of products in the specified service life and all environments (such as expected use, transportation or storage). It refers to exposing products to natural or artificial environmental and economic conditions to undergo their effects, so as to evaluate the performance of enterprise products under the environmental conditions of actual use, transportation and storage, and analyze problems to study the impact of environmental factors and their important mechanism.

Electronic components are widely used, such as thyristors (crystal control), inductor coils, transformers, crystal oscillators, earphones, resistors, capacitors, etc., which all use electronic components. IC chip appearance inspection system in the production process of IC integrated chip devices, the appearance quality inspection of the chip is an essential link, including the inspection items such as the pin size, deformity, deflection, uneven spacing and poor flatness of the chip, and the above quality problems will directly affect the quality of circuit products. Any product will produce some bad appearance in the production process, and electronic components are no exception. Then, how to do the appearance quality inspection of electronic components? The following introduction is for your reference. View >>

The quality of the crystal oscillator is directly related to the stability of the whole system. Therefore, how to select a crystal oscillator and how to view the main parameters of the crystal oscillator are compulsory courses for engineers. The selection of parameters is related to the stable operation of the system. The specific selection not only needs to control the crystal oscillator parameters in detail, but also needs to refer to the requirements of different systems. The function of crystal oscillator in the circuit is to provide basic frequency signals for the digital system. If the crystal oscillator does not vibrate, MCU will stop running, resulting in the failure of the whole circuit. View >>
