    Tin Copper Lead Free Solder Bar Advantages

    In order to obtain high-quality lead-free solder strip products and ensure that they conform to the production process of ultra pure and fine tin, Qiantian tin solder factory under strict IQC incoming inspection management, the quality of each batch must be tested and analyzed by spark source metal direct reading spectrometer spike spectolab, and the percentage of each metal component in it can be completely detected in an instant To ensure that the raw materials meet the requirements of high quality. The company uses refined tin, pure copper, high-grade oxidation resistant alloy and other refined lead-free solder bar, which has the following unique advantages:

    1. The surface of lead-free solder strip is uniform and smooth, with high purity, good fluidity and wettability after melting, bright solder joint and little oxidation residue;
    2. Low cost, excluding high price precious metals;
    3. It can adapt to the temperature that the existing wave soldering equipment and components can bear;
    4. The sensitivity to impurity elements is low;
    5. The surface concave convex phenomenon is less when cooling;
    6. The reliability of solder joint is higher than that of SnPb solder.

    Tin Copper Lead Free Solder Bar Features

    Pure tin, pure copper and pure silver are used as raw material

    According to the required alloy, it is made of pure tin, pure copper, pure silver, etc. combined with high-grade antioxidant essence. The quality of finished products is determined by the quality of incoming materials.

    According to the European standard "SGS"

    All trace elements, such as copper and tin, are refined according to the EU standard.

    Good circulation, easy tin

    Low melting point, good activity, high insulation resistance, fast tin loading speed, reduce the high temperature impact on components during welding, reduce the time of soldering tin and save working hours.

    Source factory, sufficient inventory, complete model

    The factory stock has the guarantee, the variety is complete, the delivery speed is fast, the after-sale service has the specially assigned person.

    The solder joint is bright, firm and full

    The solder joint is bright and full, with good oxidation resistance, good wettability and expansion tension, and the solder joint does not produce overseas Chinese pull point.

    Extensive Use

    It is suitable for welding led, household appliances, electronic components, computers and other products.
