The reliability of ac dc adapter is an important content to measure the quality of products. With the development of electronic technology and the increasing complexity of electronic product circuits, structures and processes, the requirements for its reliability are getting higher and higher. The traditional requirement for the content of reliability research is to design and manufacture switching power supply adapter products with fewer faults and not easily damaged.
The content of reliability technology has been developed into three aspects: maintainability technology, information technology and management technology, forming a comprehensive technology, which has been paid more and more attention by people. Reliability in the production process is an important aspect of reliability technology and plays an important role in improving product reliability. The reliability of switching power supplies includes reliability in product design, product trial production, and product manufacturing. The design of the power adaptor should comprehensively consider the three factors of product performance, reliability and price. It should not pursue high technical performance or low cost. The reliability of the product should also be considered. The product should be fully considered in the design. Repair and maintenance make the product have strong maintainability and adapt to changes in use conditions. Prototype design should ensure to maximize the use of advanced components such as integrated circuits, combinational circuits, and functional circuits, reduce the number of components and parts, simplify the realization of circuit principles, and try to keep the structure simple; try to use the tested components that have been tested in practice. Standard circuits, standard parts, avoid the use of non-standard components and parts; for components with low reliability requirements, the components can be derated and used to increase the safety factor; redundancy technology is used for components with low reliability, That is to say, the parts are multiple combined in the whole machine, and when one of the parts fails, the other part can still maintain work; organize technicians and related experts to repeatedly review and demonstrate the design. If there is only good design, no high-quality materials, especially the lack of highly reliable components, the lack of advanced production methods and manufacturing processes, and the lack of support from skilled technicians and production workers, it will make the product reliable decline. Therefore, reliability assurance measures must be taken during the manufacturing process to ensure the reliability of the Class 2 Power Supply 120vac 60hz from aspects such as personnel, materials, methods, and equipment.
