In the production and manufacturing process of PCB circuit boards and components, it is particularly important to improve the production efficiency and yield rate of chip processing. It can reduce the production of finished products for enterprises and improve the economic benefits of enterprises. The purpose of aging test is to use laboratory equipment to simulate the change of insulation performance of insulating materials under long-term operation in the shortest time. Therefore, scientists from foreign experimental research departments have done a lot of research and experimental exploration, and finally determined the experimental method of simulated accelerated aging of insulating materials.

X-ray detection technology is a new process method and analysis technology, which can complete the product defect detection that cannot be seen by the naked eye, and achieve 100% nondestructive testing, that is, it can accurately detect the internal problems of the product without causing any damage to the product. X-ray detection, with its unique advantages, has successfully attracted the attention of various industrial industries and is widely used in production lines. X-ray detection equipment is a detection method that uses low-energy X-ray to quickly detect the internal quality and foreign matters of the object to be detected, and displays the image of the object to be detected through the computer.

The outstanding feature of nondestructive testing is that it can be tested without damaging materials, workpieces and structures. Therefore, after nondestructive testing, the inspection rate of products can be very high. X-ray flaw detection and ultrasonic flaw detection are both nondestructive testing methods of nondestructive testing, and many people will ask what is the difference between x-ray flaw detection and ultrasonic flaw detection? In order to help you understand, the following contents are organized by the Core Creation Testing Network for your reference. View >>

EMC, in Chinese, refers to the ability of the equipment or system to meet the requirements in its electromagnetic environment and not cause unbearable electromagnetic interference to any equipment in its environment. EMC test, also known as electromagnetic compatibility (EMC), refers to the comprehensive evaluation of electromagnetic interference (EMI) and anti-interference capability (EMS) of electronic products, and is one of the most important indicators of product quality.

Salt spray test is an environmental test that mainly uses artificial simulated salt spray environmental conditions created by salt spray test equipment to assess the corrosion resistance of products or metal materials. It is divided into two categories, one is natural environmental exposure test, the other is artificial accelerated simulated salt spray environmental test. The artificial simulated salt spray environment test is to use a kind of test equipment with a certain volume space - salt spray test chamber, and use manual methods in its volume space to create a salt spray environment to assess the quality of salt spray corrosion resistance of products.

The quality inspection report is a written report that reflects the quality of products and projects after the quality inspection and quality supervision of products and projects are carried out according to the requirements of standardization and analysis and research. It is the result of quality inspection and the carrier of quality information feedback. In economic activities, it has become a management means to control the quality, a basis for maintaining the normal economic order of society, safeguarding the legitimate rights and interests of users and implementing arbitration. The third party inspection report is the result obtained through the quality inspection of products and equipment to ensure the product quality system standard. View >>

The testing and screening service of electronic components is also called the secondary screening of electronic components. The secondary screening of electronic components refers to the screening of electronic components by the user or its entrusted third party on the basis of the screening of component manufacturers. Secondary screening is a series of targeted tests based on various failure modes of electronic components, so as to effectively eliminate early failures. View >>
