When PCBA is welded, there are usually many requirements for PCBA plates, and the plates must meet the requirements before they can be welded. The application of special processes immediately brings about the requirements for PCB boards. If PCB boards have problems, it will increase the difficulty of PCBA welding process, which may eventually lead to welding defects, unqualified boards, etc. Welding is a very important process in PCB proofing. What are the requirements for PCB welding environment? View >>

When a mechanical part loses its working ability or fails to meet the design requirements due to some reasons, it is called failure. The results of failure analysis can not only predict the failure form of parts, but also serve as the basis for selecting materials for parts. At the same time, they can provide instructive data for reasonably formulating the manufacturing process of parts, optimizing the structural design of parts, and developing new materials and processes. This paper collects and sorts out some materials, hoping to be of great reference value to all readers. View >>

Wave soldering refers to the soldering of melted soft solders into solder peaks as required by the design by spraying them through an electric pump or an electromagnetic pump. It can also be formed by injecting nitrogen into the solder pool, so that the printed boards with components in advance can pass through the solder peaks to realize the soft soldering of mechanical and electrical connection between the component terminals or pins and the printed board pads. Next, the technical requirements and operation precautions of the down wave soldering process will be described in detail. View >>

Generally speaking, it is inevitable that errors occur in the development and production of chips. Failure analysis is a technical and management activity to judge the failure mode of the product, find out the failure mechanism and reason of the product, and put forward countermeasures to prevent re failure. With the continuous improvement of people's requirements for product quality and reliability, failure analysis is becoming more and more important. The development of society is a process of finding and solving problems. Problems are not terrible, but frequent occurrence of the same type of problems is very terrible. View >>
