In modern development, X-ray imaging technology has formed a relatively complete set of X-ray nondestructive testing technology system. "Nondestructive" as the name suggests, the test process will not damage the test piece. Its biggest feature is that it can test without damaging the material and structure of the test piece. Therefore, the use of nondestructive testing can implement 100% full product inspection to ensure production quality. This can be achieved by using Xray online detection technology, which can not only realize the detection of invisible solder joints such as BGA, but also conduct qualitative and quantitative analysis of the detection results, so as to find faults early.

Power supply IC is an indispensable component of electronic equipment. If the power supply IC is damaged in the circuit, the electronic equipment will stop working. Therefore, it is necessary to make a correct judgment on the integrated circuit. Before testing the power IC chip, we need to master the purpose, internal structure principle and main electrical characteristics of the IC in the circuit, and analyze the internal electrical schematic diagram if necessary, so as to better judge and prove whether the device is damaged. So how should we detect the power chip IC? View >>

Chip technology is the most important in the field of science and technology. Chip is just needed for any country. Chips are widely used in computers, mobile phones, home appliances, automobiles, and other electronic products and systems. Chips emphasize the integration, production and packaging of circuits. Chips are of great significance for scientific and technological innovation. Chips are everywhere and change our life all the time. No matter what equipment is inseparable from chips. Chips are mainly divided into memory chips, power chips and logic chips according to their functions, but the manufacturing process of chips is very complex, and the chip production line involves about thousands of processes. What are the working principles and functions of the chip? View >>

The appearance defect detection of electronic components is a very key link. Because such products are generally small and have high requirements for quality, it is difficult to pass the manual mass detection. It is necessary to use the visual detection equipment of electronic components for automatic appearance defect detection. The appearance equipment detection method can detect defects in real time, quickly and accurately identify scratches, greatly improve the production efficiency of the production line and improve the production quality of products.

Since its birth, welding technology has played an important role in human production and life, and covers almost all industrial industries, such as construction, heavy industry, vehicles, ships, aerospace and so on. However, defects from the inside and outside of the weld will usually lead to welding failure, such as reduced welding strength, poor welding sealing, poor weld aesthetics, etc. Nondestructive testing has a wide range of applications. The development of core technology promotes the development of nondestructive testing equipment. Nowadays, nondestructive testing equipment has gradually changed from completely relying on import to independent research and development. The quality of domestic equipment is not inferior to that of import. Especially in some industries that require product accuracy, product quality is particularly important. View >>
