As an industrial power, China has also experienced qualitative development in the industrial field. Industrial CT can be used in the field of industrial flaw detection and nondestructive testing. It can quickly and non destructively detect the internal structure, composition and defects of objects by using rays, and can clearly and accurately present two-dimensional sectional images and three-dimensional images. The images have the advantages of high resolution and high precision, can be detected in real time, and can detect large industrial components. View >>

Failure analysis can find out the failure position, failure cause and mechanism of IC chip, so as to provide product improvement direction and suggestions to prevent problems. It can find out the failure cause and preventive measures for designers, producers and users. Failure analysis provides basis for improving product design and material selection, and prevents or reduces fracture accidents; Reliability can also be predicted by failure analysis; It can improve the reputation of mechanical products and play the role of technical feedback.

Nondestructive testing is to detect the internal defects and surface defects of the workpiece without damaging the workpiece by using the changes of thermal, acoustic, optical, electrical, magnetic and other reactions caused by the abnormal internal structure of the material or the existence of defects. Welding: usually refers to the welding of metal. It is a forming method in which two separate objects are combined into a main body by heating or pressurizing, or both at the same time. Classification: according to the heating degree and process characteristics of the welding process, the welding methods can be divided into three categories. View >>

According to the failure mode and phenomenon, the general testing laboratory will simulate and reproduce the failure phenomenon through analysis and verification, find out the cause of failure and dig out the failure mechanism. It has strong practical significance in improving product quality, technology development and improvement, product repair and arbitration of failure accidents. The methods are divided into destructive analysis, nondestructive analysis, physical analysis, chemical analysis and so on. View >>

Connectors are also called connectors. Also known as connector and socket in China, it generally refers to electrical connector. That is, a device connecting two active devices to transmit current or signal. The male terminal and the female terminal can transmit information or current through contact, which is also called a connector. Connector reliability is its most important performance. When using connectors, we can record some common factors affecting connector reliability, carefully study and analyze the causes of failure, and put forward some ideas on how to improve connector reliability after finding the causes. Here we have sorted out five common causes of connector failure. Let's have a look. View >>

The development of electronic products in the direction of miniaturization, portability, networking and high performance puts forward higher requirements for circuit assembly technology and the number of I / O leads. The volume of the chip is getting smaller and smaller, and there are more and more pins of the chip, which brings difficulties to production and repair. Originally, Quad flatpack QFP was widely used in SMT, and the limit size of package spacing remained at 0.3 mm. The leads with this spacing were easy to bend, deform or break, which had high requirements for SMT assembly process, equipment accuracy and welding materials, and the defect rate of QFP with narrow assembly and fine spacing was up to 6000 ppm, which restricted the wide application.

Certification, accreditation, inspection and testing is a basic system to strengthen quality management and improve market efficiency under the condition of market economy. It is an important part of market supervision. Its essential attribute is "delivering trust and serving development", which has the prominent characteristics of marketization and internationalization. It is known as the "physical examination certificate" of quality management, the "letter of credit" of market economy and the "pass" of international trade. View >>
