With the increasing demand for miniaturization of electronic equipment, there are more and more functions of a single chip. In the prior art, in order to ensure the quality of the chip, the process from design molding to mass production usually includes the chip detection stage. However, the traditional chip debugging technology is a set of test program for the function additionally developed based on the chip function. It usually can only detect whether the chip has errors or faults, and can not accurately locate the errors in the chip terminal. It can only be judged by the experience of the tester, resulting in the slow speed and low efficiency of chip detection. View >>

Cyclic corrosion test (CCT) has been developed in the automotive industry in recent years. It is a method to accelerate the corrosion failure in the real world under the condition of laboratory control. As the name suggests, the test includes different climates, which will cycle automatically, so the tested samples will experience the same changing environment as nature. The purpose is to cause naturally occurring fault types, but faster, i.e. acceleration. By doing so, manufacturers and suppliers can more accurately predict the expected service life of their products. The lack of correlation between the results obtained by the traditional salt spray test and the "real-world" atmospheric corrosion of vehicles makes the automotive industry lack a reliable test method to predict the expected service life of its products.

Connector is an indispensable component in electronic equipment. If you observe along the current flow path, you will always find one or more connectors. It is also a component that our electronic engineers and technicians often contact. It is used to build a communication bridge between blocked or isolated circuits in the circuit, so as to make the current flow and realize the predetermined function of the circuit. With the development of society and the progress of science and technology, connectors are playing a more and more important role in various fields. In order to ensure their safety and durability, it is essential to test the reliability of connectors. View >>

What is weather resistance? Weather resistance, also known as reliability test, refers to a series of aging phenomena such as fading, discoloration, cracking, pulverization and strength decline of materials such as coatings, building plastics and rubber products due to the influence of external conditions such as sunlight, temperature change, wind and rain. Ultraviolet radiation is the key factor to promote the aging of plastics. View >>

With the continuous development of electronic and electrical products, their varieties are more and more complex and comprehensive, and China's provisions on the testing standards of electronic components are also relatively standardized. Reliability test is very important for the durability of products. For example, the reliability test of temperature and humidity can reflect the state of electronic products under extreme high and low temperatures. This test of temperature and humidity can test the impact of climate on electronic products. How to choose suitable component testing items without detours? Next, let's introduce the testing items of electronic products. View >>

Packaging testing is an important part of the semiconductor industry chain. Packaging refers to the shell used to install semiconductor integrated circuit chips, which plays the role of installation, fixation, sealing, protecting chips and enhancing electrothermal performance. The components not packaged may affect the performance, and it is also convenient for transportation after packaging. Because the quality of packaging technology also directly affects the performance of the chip itself and the design and manufacture of PCB (printed circuit board) connected with it, it is very important. How many packaging forms are there for electronic components? Chuangxin a form to teach you to understand! View >>
