In modern industry is in fact a very complex, covering many aspects of a system problem. Product design, material selection, manufacturing, testing, packing and shipping, can have an impact on product quality. Ignore any point that could make other efforts had been in vain.

Terminals in the connector part is the core of the entire part, part as a conductor, its treatment, performance stability, directly determine the quality and service life of the product. It is the role of the plug or the socket is connected by a cable of voltage and current (including power transmission and signal transmission) delivered to the corresponding socket or plug contacts component. Requirements for terminals are a number of ways. It must first have good structural strength, and also exposure remained stable, sturdy, reliable power. Of course, indispensable also has excellent conductive ability. In particular, conduction in terminals is not good, not only degrade efficiency of transmission, such as signal transmission speed, resistance is too large to damage not only the energy transmission process is too large, and temperature increases is not conducive to a system problem, planted a hidden danger for security incident.

Terminal choice of desired performance materials also needs to play its performance advantages of reasonable design. But in the current situation in the country, the lack of good design is on the one hand, backward processing technology of terminals on the other hand is also an important factor contributing to low overall product quality. Processing size large deviation, surface roughness, cemented errors, thermal treatment processes behind these reasons have caused low rates of superior products. While this lack of dedicated technical staff  have a lot to do, and some factories do not lack money, the device is the most advanced products imported from abroad, but lacked the same excellent technical operations personnel, unable to give full play to the new device, the advantages of new technology, quality cannot be improved to a higher level of terminals.

Elinker analysis of influencing the quality of Terminal products also has day-to-day management. It covers not only production, testing links, products, packaging, storage and transportation, if relevant personnel lack sufficient training and sense of responsibility, can easily be in the hands of products not yet delivered to the user when a problem occurs.
