Matte tin connector Features: Exterior is foggy, crystallization rough, easy to leave fingerprints, general thickness 5um, 8um, or even higher, depending on its use, ranging plating thickness. Weldability and corrosion properties of tin whiskers brighter than matte tin tin to be good, but afraid of scratches, fingerprints and other fear. Connector bright tin Features: Exterior is bright, relatively good-looking, relatively smooth, fine crystal, not easy to leave fingerprints connector manufacturers, general thickness 3um more. General purely functional pieces will choose matte tin, but belong to the appearance of pieces need to solder will choose bright tin. Temperature change the physical state of the object, which is affecting the effectiveness of the connector is a strong factor connector lights, due to the different seasons, geographical differences, the ambient temperature can vary a lot, but after communicating connector terminal connector of two components, the current will be generated when the heat causes the temperature to rise after that the two together is the operating temperature. A good metallic component within the connector should be able to maintain the physical state at a certain temperature does not change, thus ensuring its high potency. Usually provides, it should be able to withstand up to 200 degrees, the minimum of minus 65 degrees. Humidity on the connector is actually water impact. Because the water is corrosive to metal components connectors, also has a certain conductivity, can reduce the insulation resistance, and therefore the connector assembly material must use water with minimal impact.
