Put the electronic components together with something like a belt. Reel the tape on a disc. This is IC braiding. IC, that is, integrated circuit, uses semiconductor manufacturing process to make many transistors, resistors, capacitors and other components on a small monocrystalline silicon chip, and combine the components into a complete electronic circuit according to the method of multi-layer wiring or tunnel wiring. In the circuit, it is represented by the letter "IC" (also with the word symbol "n", etc.). View >>

With the emergence of new technologies, coupled with high profits and low risks, IC chip counterfeit products have become more complex and rampant. When there is a shortage of components, in order to ensure the uninterrupted supply of components, many companies may also look for unauthorized informal sources, but it exacerbates the existing problem of component counterfeiting. Nowadays, the proliferation of counterfeit electronic components has become a major pain point in the component industry. How to distinguish whether the purchased components are counterfeit through appearance? How to identify the authenticity of components? View >>

Reliability test refers to measuring and verifying the reliability of products through tests. The research finds out the weak links of products under the condition of limited samples, time and use cost. Reliability test is the general name of various tests carried out to understand, evaluate, analyze and improve the reliability of products. The test to measure, verify or improve product reliability is called reliability test. It is an important link of product reliability. View >>

Single chip microcomputer burning, also known as single chip microcomputer program download and burning, is essentially a process in which the single chip microcomputer and PC transmit the compiled program to the single chip microcomputer through the interface specified by the chip manufacturer according to the programming protocol specified by the chip manufacturer, and the single chip microcomputer stores the data in its own memory. In embedded systems, it is often necessary to burn code or data to MCU on-chip flash or off-chip nor flash, NAND flash, SPI flash, etc. What is the burning principle of single chip microcomputer? Which method is the best for the product? Here are several chip burning methods. View >>

As the source power of the rapid development of modern electronic information technology industry, chip has been widely penetrated and integrated into every field of national economic and social development. It is an important support for the digital economy, information consumption and even the long-term development of the country. BGA is an indispensable part of electronic components, but voids often occur in BGA packaging and welding. The generation of voids is mainly due to the bubbles generated by the organic matter in the flux after high-temperature cracking, resulting in the gas being surrounded in the alloy powder to form voids. The generation of voids will affect the use effect of the product to a certain extent, For example, the welding cavity is easy to cause poor contact to electronic components in the later use process and affect the service life. Today, we will introduce several common detection methods for BGA Solder joint defects or failures to help you deeply understand and do View >>

Program burning is to load the original program into the computer after compilation and processing, and let the computer execute the program you write. For example, when the MCU program is burned, it is loaded Hex file, stored in the single chip microcomputer, can realize the written program when starting up. In short, the process of enabling the microcomputer to start up and execute your program is program burning. Program burning is to carve the desired data into media such as optical disc, burn card (GBA) through recorder and other tools. There are DVD-R / DVD-RW, DVD + R / DVD + RW and other disc recorders in different formats on the market, which can be used to record and permanently save data, which can greatly facilitate the storage of data. The maximum speed supported for disc recording is 20x. View >>

In the field of consumer electronics, the quality standards of the components used are becoming more and more strict. With the wide use of semiconductor devices, their service 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.
