Whether electronic equipment can work reliably is based on whether electronic components can work reliably. If the early failure components are installed on the whole machine and equipment, the early failure rate of the whole machine and equipment will be greatly increased, its reliability can not meet the requirements, and it will have to pay a great price for maintenance. Therefore, before the electronic components are installed on the whole machine and equipment, we should try to eliminate the components with early failure as much as possible. Therefore, we should screen the components. View >>

Components shall be screened according to relevant screening technical conditions and can be used only after passing the screening. In order to prevent false welding caused by oxidation at the welding end after screening of chip components, it is forbidden to screen chip components without weldability treatment conditions at the welding end. Components are the basis of the whole machine. The inherent reliability of electronic components depends on the reliability design of the product. In the manufacturing process, it may form time or stress-related failure in use due to its inherent defects or improper control of manufacturing process. In order to ensure the reliability of the whole batch of components, we should try to eliminate the components with early failure as much as possible before the electronic components are installed on the whole machine and equipment. Therefore, we should screen the components. View >>

Chip testing needs very professional equipment. In order to strengthen the supervision of inspection and testing institutions and facilitate social inquiry and supervision, the General Administration of market supervision began to provide the society with online inquiry service on the number validity of inspection and testing reports. How to view the authenticity of a third-party test report? What is the purpose of the inspection report? How to distinguish the authenticity of the inspection report? First of all, let's talk about the test report. Before the goods are sold on the market, manufacturers and businesses need to provide products to an authoritative third-party testing organization for product quality testing. The qualified product organization will issue a quality testing report to recognize the quality of the manufacturer's products. Such products meet the needs of listing and customers. In short, it is not only a consumer service guarantee for consumers, but also a product quality guarantee for businesses View >>

Wear is a phenomenon of continuous damage caused by the gradual separation of wear debris on the surface when the object moves relatively under the action of friction. Wear failure refers to the failure of mechanical parts to reach the original design efficiency due to the occurrence of wear phenomenon, that is, they can not reach the original design level. Wear failure is a process of gradual development and gradual change, ranging from a few hours to a few years. Wear, fracture and corrosion are called three forms of metal failure analysis, and their harm is very amazing. View >>

Corrosion failure corrosion refers to the damage phenomenon caused by chemical or electrochemical reaction on the surface of metal or alloy materials. Although metal corrosion plays a beneficial role in pickling, chemical power supply, electrochemical machining, metallographic etching and so on, it has caused serious losses in the national economy. Because corrosion is the phenomenon that mechanical components lose their original design function, it is called corrosion failure. View >>

CNAs (China National Accreditation Service for conformity assessment) is the abbreviation of China National Accreditation Commission for conformity assessment. It is a national accreditation institution approved and authorized by the state certification and Accreditation Administration Commission in accordance with the provisions of the regulations of the people's Republic of China on certification and accreditation, and is responsible for the accreditation of certification institutions, laboratories, inspection institutions and other relevant institutions. CNAs laboratory accreditation is a formal recognition of the laboratory's ability to carry out specified types of testing and / or calibration. View >>

Q: What is recognition? A: Accreditation is a third-party certificate formally indicating that the conformity assessment institution has the ability to carry out specific conformity assessment. Generally speaking, accreditation means that the accreditation institution reviews the conformity assessment institutions engaged in certification, testing and inspection in accordance with relevant international or national standards, confirms that they meet the requirements of relevant standards, further proves that they have the technical and management ability to engage in certification, testing and inspection, and issues accreditation certificates.

The screening requirements of component users are generally determined by the overall model unit. The secondary screening of components is a supplement to the primary screening. The service conditions and application environment of components shall be comprehensively considered on the basis of the items and stress of the primary screening. Because each unit undertakes different tasks and has different requirements for product reliability, there is no unified screening specification standard. View >>

Electronic components are an integral part of electronic products. Affected by the quality of electronic components, the quality and performance of electronic products will also change. Since the 1950s, reliability technology research has sprung up abroad, while it has developed since the early stage of reform and opening up in China. Through reliability test, the reliability characteristic quantity of electronic products working or stored under various environmental conditions can be determined to provide useful data for use, production and design; It can also expose the problems existing in the design, raw materials and process flow of the product. Through a series of feedback measures such as failure analysis and quality control, the existing problems of products can be solved gradually and the reliability of products can be improved View >>

DPA detection (destructive physical analysis) is the whole process of verifying whether the design, structure, material and manufacturing quality of components meet the requirements of the intended use or relevant specifications, sampling according to the production batch of components, dissecting the samples, and a series of inspection and analysis before and after dissection. It can determine whether there may be quality problems of component batches that endanger the use and lead to serious consequences. DPA technology is widely used in military and civil electronic components. It is of great significance in procurement inspection, incoming inspection and quality monitoring in the production process.
