Machine vision is a branch of artificial intelligence, which uses machines instead of human eyes to measure and judge. Driven by the demand for industrial automation and intelligent manufacturing, the penetration of machine vision downstream applications has increased, and the industry space is broad. At present, the application of machine vision solution is extending from industrial field to non industrial field to realize the positioning, detection, measurement, recognition and judgment of things.

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 >>

Since the beginning of the year, chip shortage and price rise have continued, seriously affecting the order of the electronic industry chain. In September, the price rise trend of the whole industrial chain was active, including original factories, chip foundry and silicon wafer factory. Under the situation of shortage and rising prices, there are frequent chaos such as hoarding and speculation, which has been widely discussed View >>

A variety of practical identification methods for the quality of electronic components. The failure of equipment and instruments is mostly caused by the failure or damage of electronic components, so the detection of electronic components is particularly important. Here, Chuangxin Xiaobian gives you an inventory of 15 practical identification methods for the quality of common electronic components. A large number of various types of electronic components are used in electronic equipment. Most of the equipment failures are caused by the failure or damage of electronic components. Especially for beginners, it is necessary to master the detection methods and experience of common components. The following are some common electronic components testing experience and skills, hoping to help you. View >>

During the processing of electronic products, due to the complex processing and extensive use of component materials, both processing defects and component defects can be divided into obvious defects and potential defects. Obvious defects refer to those defects that cause the products to fail to work normally, such as short circuit / open circuit. The potential defects lead to the temporary use of the product, but the defects will soon be exposed in use, and the product can not work normally. Potential defects cannot be found by conventional inspection methods, but eliminated by aging methods. If the effect of aging method is not good, the potential defects that have not been eliminated will eventually appear in the form of early failure (or failure) during product operation, resulting in an increase in product repair rate and maintenance cost.

Solderability means that under the action of welding heat, the solder, weldment and copper foil will not melt, and the solder will melt and wet the welding surface, resulting in the diffusion of solder metal, forming a metal attachment layer between the copper foil and weldment, and connecting the copper foil and weldment together to obtain a firm and reliable welding point, The above process is the effect of mutual physical interaction process. If it can completely infiltrate with tin, it is good weldability. Otherwise, it is necessary to judge the weldability according to the effect. View >>

Generally speaking, mistakes in the process of R & D and production of chips are inevitable, just like making up for the lack of room. Where there is a problem, you just have to solve the problem and think about why there is a problem. With the continuous improvement of people's requirements for product quality and reliability, failure analysis is becoming more and more important. The development of society is a process of finding and solving problems. The emergence of problems is not terrible, but the frequent occurrence of the same kind of problems is very terrible. This paper mainly discusses how to carry out effective chip failure analysis solutions and common analysis methods. View >>

Weldability refers to the difficulty of material welding operation, joint performance, and the weldability of electronic components. Oxidation or pollution is easy to occur on the welding end or pin surface of components. In order to ensure the welding reliability, attention must be paid to the packaging conditions and environmental conditions of components during transportation and storage. Measures should also be taken to prevent components from being exposed to the air for a long time before welding and to prevent them from being stored for a long time. Together, attention should be paid to the solderability test before welding, So as to find and deal with problems in time. There are many methods to test the solderability of components. The following is a brief introduction to several commonly used test methods. View >>

Electronic components are an integral part of electronic components and small electrical machines and instruments. They are often composed of several parts and can be used in similar products; It often refers to some parts of electrical appliances, radio, instruments and other industries, such as capacitors, transistors, hairsprings, clockwork and other sub devices. Common are diodes and so on. In the manufacturing industry, the four main items that have a direct impact on product quality are usually design, incoming materials, manufacturing process and storage and transportation. Generally speaking, design accounts for 25%, incoming materials for 50%, manufacturing process for 20% and storage and transportation for 1% to 5%. To sum up, incoming material inspection plays an overwhelming role in the company's product quality, so we should raise the factory's incoming material quality control to a strategic position. View >>
