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.

What does UV testing mean? Ultraviolet ray, abbreviated as UV, is translated into Chinese: ultraviolet. Anti UV test is "anti ultraviolet aging test". Ultraviolet will lead to aging of equipment shell. Equipment exposed outdoors usually needs to be tested. It mainly imitates the natural sunlight environment and reproduces the damage caused by sunlight, rain and dew. The equipment carries out the test by exposing the material to be tested to the controlled interactive cycle of sunlight and moisture and increasing the temperature at the same time. It is used to evaluate the changes of materials in color change, gloss, crack, foaming, catalysis, oxidation, etc. It is mainly used in the aging experiment of non-metallic materials with sunlight resistance and artificial light source. This method is effective because short wave ultraviolet light is the main cause of outdoor material aging View >>

3. Comprehensive test refers to the test that integrates the three environmental stresses of temperature, humidity and vibration. This test is used to assess the adaptability of products to transportation and use in the environment of temperature, humidity and vibration. Compared with the effect of single factor, it can more truly reflect the adaptability of electrical and electronic products to the changes of temperature, humidity and vibration compound environment in the process of transportation and actual use, and expose the defects of products. It is an indispensable important test means in the whole process of new product development, prototype test and product qualification test. There are also impact and collision. The specific matching test depends on the customer's requirements. View >>

The mechanical impact test mainly simulates the impact effect that the equipment and its components may encounter during transportation or use, and analyzes the ability of the product to withstand the external impact environment through the instantaneous transient energy exchange of the shock wave. The purpose of the test is to understand its structural weakness and functional degradation, which is helpful to understand the structural strength, appearance, impact resistance, drop and other characteristics of the product. Effectively evaluate the reliability of products and monitor the consistency of products in the production line. View >>

Drop test, also known as "packaging drop tester": it refers to the situation when different edges, angles and surfaces fall to the ground at different heights after product packaging. So as to understand the damage of the product and evaluate the degradation height and impact strength that the product packaging components can bear when falling. So as to improve and perfect the packaging design according to the actual situation of the product and within the scope of national standards. View >>
