Terminal is used to realize electrical connection of a kind of accessories products, industry is divided into the category of connector. With the increasingly high degree of industrial automation and industrial control requirements more and more strict, accurate, the amount of terminals gradually increased. With the development of electronic industry, the use of terminals is more and more, and more and more kinds. The most widely used in addition to PCB board terminals, hardware terminals, nut terminals, spring terminals and so on.

Terminal gradually widely used in various fields, in the transmission of electrical signals and electricity plays a role in the connection, thus reducing the workload and production cost consumption, production and use to bring a lot of convenience, avoid a lot of trouble. So as to achieve the purpose of simplifying product structure and saving manufacturing cost. Therefore, in view of the benefits of terminal detection and combined with market analysis, recommended suitable terminal detection instruments can be professional detection equipment for detection. Commonly used terminal detection equipment: tool microscope and optical imaging instrument.
