Before failure analysis, it is necessary to narrow the scope of suspicion according to the failed products and their failure background, preliminarily judge the possible failure phenomena of products, select appropriate analysis technology and equipment, follow the principle of simplicity before complexity, from outside to inside, from face to point, from non-destructive to destructive, clarify the analysis sequence and formulate targeted analysis scheme, Reduce the cost of failure analysis, speed up the progress of failure analysis and improve the success rate of failure analysis. Prepare corresponding treatment measures for various possible causes. View >>

Generally, the failures of electronic components are called failure. Knowing the failure mode and mechanism of components and the mechanism of equipment failure is very important for diagnosing equipment failure and maintaining the inherent reliability of equipment. The purpose of component failure analysis is not only to judge the failure nature and clarify the failure cause, but also to find an effective way to actively prevent repeated failure. Let's take a look at the main steps of component detection methods and failure analysis. View >>

Failure analysis is a new developing subject, which has been popularized from military industry to ordinary enterprises in recent years. It is generally based on the failure mode and phenomenon, through analysis and verification, simulate and reproduce the failure phenomenon, find out the cause of failure, and dig out the failure mechanism. Failure analysis is a necessary means to determine the failure mechanism of chip. Failure analysis provides necessary information for effective fault diagnosis. Failure analysis provides necessary feedback information for design engineers to continuously improve or repair the chip design and make it more consistent with the design specification. Failure analysis can evaluate the effectiveness of different test vectors, provide necessary supplements for production testing, and provide necessary information basis for verification and test process optimization.

Nondestructive testing is to use the acoustic, optical, magnetic and electrical properties of materials to detect whether there are defects or non-uniformity in the tested object without damaging or affecting the service performance of the tested object, and give information such as the size, location, nature and quantity of defects. Nondestructive testing can find defects in the interior and surface of materials or workpieces, measure the geometric characteristics and dimensions of workpieces, and determine the internal composition, structure, physical properties and status of materials or workpieces. What are the characteristics of NDT? What is the principle? View >>

Casting inspection is the operation process of inspecting whether the casting is qualified by visual inspection, measuring tools, instruments or other means according to the user's requirements, drawing technical conditions and other relevant agreements. Due to the coarse grain, poor sound permeability and low signal-to-noise ratio of the casting, flaw detection will be more difficult. It uses the sound beam with high-frequency sound energy to reflect when it encounters the internal surface or defects. The reflected sound energy is a function of the directivity and nature of the inner surface or defect and the acoustic impedance of this reflector. Therefore, the sound energy reflected by various defects or inner surfaces can be used to detect the location, wall thickness or depth of defects under the surface. View >>

Now, with the continuous improvement of people's requirements for the quality and reliability of electronic products, the requirements for the quality of chips are becoming higher and higher. Chip failure is inevitable in the process of development, production and use. Therefore, chip detection and analysis is becoming more and more important. As the appearance of forged electronic components becomes more and more realistic, it can not be distinguished by the naked eye. It is also at this time that X-ray test equipment appeared. Compared with traditional destructive physical analysis and fault analysis, X-ray has the advantages of timeliness, cost and professionalism. They have obvious advantages. View >>

Modern industrial production is inseparable from the use of various machinery. With the acceleration of the pace of industrial production, the loss of various parts in mechanical equipment is increasing. Once there is a defect, it will cause hidden dangers to mechanical equipment and may also pose a threat to the life safety of producers. Therefore, the defect detection of mechanical parts is very important. Mechanical equipment parts are indispensable basic conditions for modern industry. View >>

Nondestructive testing industry has a history of decades in China. With the development of social economy, nondestructive testing industry has been involved in all aspects of people's life. Some experts once said that NDT is a sunrise industry. There is a lot of room for development in this industry, especially in China. Product inspection has also changed from the era of human eyes to the era of machines. However, the smaller the product size, the higher the requirements for inspection equipment. Among them, nondestructive testing technology plays a vital role in the development of industrial field. View >>
