In recent years, the progress of science and technology makes the X-ray detection equipment used in production more strict. Crankshaft, cylinder, engine blade and other industrial parts also use castings. The production of castings is very easy to produce bubbles and other problems, which can not be solved by traditional technology. However, the nondestructive testing technology of X-ray testing equipment has obtained very accurate results in the testing of various castings, has a wide range of applications, and the technology is mature.

Generally speaking, the test conducted to evaluate and analyze the reliability of electronic products is called reliability test. It is to predict the quality from the delivery of products to the end of their service life. After selecting the environmental stress with high similarity to the market environment, set the degree and application time of environmental stress. The main purpose is to correctly evaluate the reliability of products in a short time as possible. View >>

Common reliability design principles and methods include component selection and control, thermal design, simplified design, derating design, redundancy and fault tolerance design, environmental protection design, robust design and human factor design. Except that component selection and control and thermal design are mainly used for reliability design of electronic products, other design principles and methods are applicable to reliability design of electronic products and mechanical products.

With the rapid development of chip design industry, a large number of chip types have been designed, but only a few of them will be large-scale streaming, and many chips are still in the design stage. This means that a large number of chip testing requirements have not been met. For a long time, the chip testing industry has been regarded as a part of chip packaging and testing. The real situation is that the traditional integrated sealing and testing enterprises are not enough to meet the current needs. View >>

With the development of the connector industry to today's level, you can start from many aspects to understand the quality of the connector. For example, among the three basic properties of the connector, the electrical performance belongs to the internal performance and the core of function play, while the mechanical performance and environmental performance can belong to the external performance.

Generally, there will be specifications on the IC, that is, IC datasheet. The datasheet will generally indicate whether the IC is an OTP component. OTP itself is also the abbreviation of one time programmable. One time means one-time and programmable means burning. If it is not a new material, first remove the old program in the original IC. After removal, you also need to check whether the program has been cleared, whether it is empty or not, and then burn it again. Burning is to program data and programs into IC. After burning, we also need to check whether the IC burned is correct, and then do encryption or write protection. View >>

At present, many electronic product manufacturers specially polish the printing on the surface of one or more IC models in their products in order not to let others know the IC chip models used in their products. The model of computer chips can also be determined through the detection of drivers and third-party software, but computer chips are rarely polished in the main board factory. So how to detect the model after the chip is polished? In order to provide you with more knowledge about IC models, let me introduce you to the following related contents. View >>

When it comes to chips, we all know that this is a very high-tech and professional field, and the whole production process is particularly complex. Goods on the market generally go through three stages: design, manufacturing and packaging. Integrated circuit chip is an integrated circuit formed by a large number of microelectronic components (transistors, resistors, capacitors, etc.) on a plastic base to make a chip. IC chip includes wafer chip and packaging chip. The corresponding IC chip production line is composed of wafer production line and packaging production line. How to distinguish between true and false IC products? Let's introduce it to you. View >>

Electronic component testing is the application of testing service industry technology in electronic information industry. It is an important link in the specific industrial chain of electronic components. The level of testing service technology is closely related to the quality of electronic components. Electronic technology is an emerging technology developed at the end of the 19th century and the beginning of the 20th century. It has developed most rapidly and widely used in the 20th century, and has become an important symbol of the development of modern science and technology. How to accurately and effectively detect the relevant parameters of components and identify the quality of components must adopt different methods according to different components, so as to judge whether the components can work normally.
