Reliability test is a means to investigate, analyze and evaluate the reliability of products. The test results provide a basis for fault analysis, research and answer, study the corrective measures taken, and judge whether the product meets the index requirements. According to the method and purpose of reliability statistical test, reliability statistical test can be divided into reliability verification test and reliability measurement test. Reliability measurement test is a test for measuring reliability characteristics or their values, which is usually used to provide reliability data. Reliability verification test is used to verify whether the reliability characteristic value of equipment meets the specified reliability requirements. Generally, reliability identification and acceptance test are collectively referred to as reliability verification test. View >>

General electronic components have corresponding technical parameters, which can be obtained from the standards of electronic components and the technical data provided by the manufacturer. The detection of components is an essential basic work. How to accurately and effectively detect the relevant parameters of components and judge whether the components are normal is not a stereotype. Different methods must be adopted according to different components to judge whether the components are normal or not, and there are different types of tests. View >>

With the rapid development of modern industry and the working status of high temperature, high pressure, high speed and high load, nondestructive testing technology has become the rigid demand of modern industry. As the name implies, "nondestructive" will not damage the test piece during the testing process. Its biggest feature is that it can be tested 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. Nondestructive testing refers to the use of changes in heat, sound, light and reaction caused by abnormal or defective internal structure of materials, such as electricity, magnetism, physical or chemical methods, with the help of modern and equipment, surface and internal structure of samples, properties, status and defect types of inspection and test methods nature View >>

All personnel performing non-destructive testing need to obtain authorized training and certification. According to European, international and American standards such as EN ISO 9712 and ASNT, China SGS NDT training center provides first-class training, assessment and certification. The successful operation of NDT technology requires sufficient training and experience. In some cases, when standards, regulations or regulations require the certification of NDT personnel, many people will certify their personnel according to the international standard ISO 9712. However, since NDT falls within the scope of different regulatory systems, so does certification and training. Although there is no central, ultimate training institution for NDT, the training program is still available. The training courses are self-taught by product manufacturers, third-party organizations and employers View >>

In many industries around the world, nondestructive testing is required by law. Nondestructive testing refers to the testing technology of defects, chemical and physical parameters of materials, parts and equipment by using principles and technical instruments such as ray, ultrasonic, infrared, electromagnetic and terahertz nondestructive testing without affecting the future use function or current operation state of the tested object. Common methods include ultrasonic detection of cracks in welds. Nondestructive testing society of China Society of mechanical engineering is an academic organization of nondestructive testing in China, and tc56 is its standardization organization. View >>

Electronic parts are electronic parts and parts of small motors and instruments. They are usually composed of several parts and can be used in similar products. With the continuous progress of modern technology, the appearance of forged electronic components becomes more and more realistic, which can not be distinguished by the naked eye. At this time, X-ray test equipment appeared. Compared with the traditional destructive physical analysis and fault analysis, the advantages of X-ray lie in timeliness, cost and professionalism.

The structure of electronic devices is becoming more and more fine and smaller. Ng or OK of X-ray fluoroscopy products is essential. The X-ray detector for X-ray fluoroscopy of electronic components is widely used as a precision test equipment in battery, led, SMT, semiconductor, casting, automotive electronics, ceramic products, plastics, connectors and other industries. Xray testing is a non-destructive testing equipment that uses X-rays to penetrate products and scan products. It is of great significance for the detection of abnormal internal structure of products. Now, with the market's attention to product quality, more and more product quality testing instruments have attracted people's attention, such as size measuring instruments, testing instruments, etc. View >>
