Fuse is a common electronic component. Fuse is also called current fuse. Iec127 standard defines it as "fuse link". It mainly plays the role of overload protection. It is a very key component in electronic products, which plays a protective role in circuit safety, so as to effectively ensure that when the product is powered on, it will not be broken down by excessive current and damage the electronic products.

Chip R & D and manufacturing is one of the important high-tech technologies. Through the change of chip technology, the technical content of electronic products has been improved. However, after the chip is packaged, its internal structure cannot be checked by naked eyes. For such precision products, there are often fake and shoddy defects. So, can X-ray technology identify true and false chips? In order to help you better understand, this paper will summarize the defect detection of IC chip. View >>

The reliability of the power module itself is very important and can be used for power applications of digital or analog loads. But in fact, due to the complexity of the working environment of the power supply system, if there is no reliable system application design, the power supply will eventually fail. Because of its high reliability, small size, high power density and high conversion efficiency, the design of power supply system becomes simpler and simpler, so it is widely used. The following introduces the main design measures and methods of power module reliability. Let's have a look. View >>

When it comes to electronic components, everyone should be familiar with them. What about the reliability of electronic components? The reliability of electronic components is an important factor affecting the reliability of products. Engineers need to select electronic components in circuit design, an essential part of which is the reliability of electronic components, and the inherent reliability of electronic components is the most easily ignored. Therefore, in order to ensure the reliability of products, we must ensure the reliability of electronic components. View >>

There are thousands of kinds of C chips, and their functions are also diverse. What's more, now more and more advanced all kinds of SOC and AI chips, the traditional function and performance test, facing the increasingly complex IC design, can achieve more and more limited results and low coverage. With the increasing demand for miniaturization of electronic devices, the functions of single chip are increasing. View >>

Nondestructive testing is a testing technology to check the internal or surface defects of materials without damaging the tested materials, or to determine some physical quantities, properties and organizational states of materials. Nondestructive testing technology is needed in almost all areas of manufacturing, service, maintenance or overhaul inspection. At present, there are many kinds of nondestructive testing technologies in practical application. In addition to the five conventional nondestructive testing methods of ray, ultrasonic, magnetic particle, penetration and eddy current, there are also microwave, acoustic emission, laser, infrared and so on. The following introduces the classification and differences of several commonly used nondestructive testing applications. View >>

When a mechanical part loses its due function, it is said to be invalid. There are many reasons for failure, such as fracture, deformation, surface wear and so on. The so-called failure mainly refers to the phenomenon that the part loses its specified function due to the change of its size, shape or material structure and performance for some reason. In order to help you have an in-depth understanding, this paper will summarize the relevant knowledge of part failure analysis. If you are interested in what this article will cover, read on.

IC chip, English name integrated circuit chip, is to put the integrated circuit formed by a large number of microelectronic components (transistors, resistors, capacitors, etc.) on a plastic base to make a chip. At present, the quality of IC chips plays a very important role in the whole electronic products. It directly affects the quality problems of the whole products after they go on the market. So for the purchasing staff, how to correctly detect the quality of IC chips? This paper briefly introduces several methods. View >>
