Why we YZK products has been emphasized and maintains a gold-plated terminal? Not that we are unwarranted using expensive material to increase the cost of products, but gold-plated material we can increase the stability of the connector.

General connector products will adopt tinning way, because tin is cheaper, better corrosion protection function, at the same time tin texture is relatively soft, is conducive to the plug and socket relatively good fit. But it is precisely because tin is soft so in multiple plug will make tin surface having relatively large wear, thereby causing the contact end deformation, so as not to design contact force, at the same time tin will produce working temperature is not up to the requirements of the situation.

There are some way is plated brass or bronze tinned working temperature to 110 ℃, steel tin can reach 190℃. The plug-pull time, generally need to gold. For higher temperature, we need other coatings, such as copper nickel application of up to 340 degrees, brass or bronze plating up to 250 degrees.

While we YZK industrial connector is mainly used for high reliability requirements of the small signal application, requires little contact force application, multiple plug, so we typically use the gold, and gold corrosion performance is also very prominent. Nickel plated layer are used, steel contact most nickel ( must first copper ). Palladium electric conductivity than gold must be bad, for replacing the electric plating in certain limited range . At present, the sustained rise of gold, palladium nickel alloy products are more and more. Silver contact has very good electrical conductivity, but silver is easily oxidized, so only under special circumstances to choose. Gold Plated industrial connectors except in corrosion protection in other ways than superior to outside, due to the wear resistance, ductility and other characteristics, also greatly enhance our product pulled. Ensure the multiple plug after still can maintain a high contact force, so as to better guarantee the electrical conductivity and the continuity of the signal. The last point is the gold there is nothing comparable to this conductive properties. This is our world, choose gold as industrial connectors electroplating materials are important reasons.
