Electronic connecting wires are one of the components that connect electrical circuits. They mainly play the role of electrical connection and signal transmission between devices and components, components and cabinets, systems and subsystems, and keep the signal distortion and energy loss between systems. Their quality is related to the reliability of the overall operation of the system equipment. They are important supporting products of host manufacturers, and their technical characteristics are greatly affected by the technological development of downstream industries. A complete connector product generally goes through three processes: design, manufacturing, and packaging/assembly.
