The right touch coating both can satisfy the application requirements, but also need to meet the functional requirements.In view of the use of the complexity of the environment, suitable coating often need to consider the best compromise between performance and reliability.In general, ordinary metal coating for high contact pressure.Precious metal coating is applied to a high density connector, long life cycle requirements.WAIN from the connector manufacture of various aspects of the products, from design began to eliminate the effect factors on the quality of the electroplating, each production process to adopt scientific management way, at the same time, use as far as possible the electroplating of the advanced equipment and the technology, and according to the cause of the problem in the plating process improvement, to ensure the connectors coating quality.
