By analyzing the composition of metal materials, we can understand the composition of materials, so as to monitor the product quality, analyze the products with problems, analyze the causes and eliminate hidden dangers. Metal materials are widely used in aviation, machinery, computer hardware and other fields. Generally speaking, metals are divided into pure metals, alloys, special metals and other types, but with the increasing demand for metal materials in various industries, there are more complex materials. The following is a share of metal material composition detection and analysis methods to better apply them to products. View >>

Polymer materials, as the name suggests, are materials based on polymer compounds. The polymer material industry should not only provide a large number of new products and materials with rapid changes for industrial and agricultural production and people's clothing, food, housing and transportation, but also provide more and more effective high-performance structural materials and functional materials for the development of high technology. The component analysis of polymer materials is a process of qualitative and quantitative analysis of unknown components of samples to be tested through a variety of separation technologies and various analytical instruments. Since the composition analysis of polymer materials is so complicated, it is very important to choose the appropriate analysis method. The following mainly introduces the composition detection and analysis methods of polymer materials for your reference. View >>

The device or measure to prevent the working medium from leaking out of the pump or to prevent external impurities or air from invading into the pump is called sealing. The sealed medium is generally liquid, gas or dust. Mechanical seal, also known as end seal, has a pair of end faces perpendicular to the rotation axis. Under the action of fluid pressure and compensating the external elastic force of machinery, the end face keeps fit with the other end and slides relative to the other end depending on the cooperation of auxiliary seal, so as to prevent fluid leakage. Mechanical seal failures are generally caused by leakage, wear and torque caused by abnormal changes. The main reasons for mechanical seal failure are as follows: View >>

Ceramic capacitor takes electronic ceramics as the dielectric material. It has the advantages of high service temperature, large specific capacity, good moisture resistance, small dielectric loss and wide selection of capacitance temperature coefficient. It is widely used in electronic circuits. However, with the extension of time, the dielectric aging phenomenon of ceramic capacitors will appear, which should be paid attention to in use. View >>

With the increasing requirements of industrial, military and civil departments for the quality of electronic products, the reliability of electronic equipment has attracted more and more attention. Screening electronic components is one of the most effective measures to improve the reliability of electronic equipment. The purpose of reliability screening is to select highly reliable components from a batch of components and eliminate products with potential defects. Broadly speaking, in the production process of components, various process quality inspections and electrical parameter tests of semi-finished products and finished products are screening, and what we are talking about here is the reliability screening specially designed to eliminate early failure components.

The test conducted to evaluate and analyze the reliability of electronic products is called reliability test. It simulates the environmental accelerated test according to the factors such as different use environments and stress of different environments that the products may encounter in the use process, so as to evaluate the performance and adaptability of products or sample materials, and provide quantitative technical indicators of environmental adaptability of products or sample materials for scientific researchers and product development engineers.

The rapid development of electronic component technology and the improvement of reliability have laid the foundation of modern electronic equipment. The fundamental task of component reliability is to improve the reliability of components. Generally speaking, the failure of electronic products in the narrow sense refers to the phenomenon of the loss of function of mechanical and electrical products, while failure analysis is to analyze and diagnose the mode, causes and mechanism of failure, and study the technical and management activities of taking remedial, prediction and preventive measures. At the same time, the comprehensive discipline intersecting with related theories, technologies and methods is called failure science. 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. 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. The reason for the high early failure rate is that there are unqualified parts in the product; The reason for the high late failure rate is that the product components enter the failure period after long-term use. The running in of mechanical products and the aging screening of electronic components are the measures to ensure reliability according to this failure law. View >>
