Sn-Ag lead free solder is developed as an alternative of lead solders. Generally, commercial tin/silver alloy contains 3% to 5% silver. The Sn/Ag series solders are widely used in soldering electronic assemblies; besides, it is applicable for soldering of jewelry due to its solder point is of high brightness. Unlike the conventional lead solders, they can be utilized in pipe joints which have contact with water and foodstuffs. Sn-Ag lead free solder is featured with high melting point and strong thermal strength. As professional tin silver alloy solder maker, we provide various Sn-Ag solders. The typical product is Sn95Ag5 tin silver solder wires and bars.

Different types of solder is different additives, additives to improve the solder in the soldering part of the auxiliary heat conduction process, removal of the oxide, reduces the surface tension of the material to be welded, the welding material of surface oil is removed, increase the welding area. Tin solder alloy wire characteristics with a certain length and diameter, can be used in conjunction with the electric iron soldering of electronic devices.
Lead-free solders generally available manufacturing method of the casting, i.e., said heavy metal raw materials, and heated and stirred in air melt in a crucible or pot. Solder alloy prepared by the method of the invention, its advantages First, reduce the melting point of the solder alloy, generally less than 200 ℃; Second, the solid-liquid phase difference between the alloy up the following 2 ℃, avoid isolated spot defects; Third alloy homogeneous, the alloy strength increases; Fourth spreading rate of the solder alloy can
