QT-6337T Lead Solder Bar Advantages

Features: suitable for wave soldering, less slag, good fluidity, reliable solder joint, bright and full.

The production of solder bars in Qiantian tin factory is different from the general casting process, because a large amount of solder slag, or non molten tin, will be produced in the wave soldering furnace by the general casting process. In the process of operation, it is easy to produce large lumps of solder like tofu dregs, and the melted solder surface will be transformed into yellow and brown solder blocks in a short time.

In order to avoid this kind of situation, Qiantian tin factory adopts unique melting, casting, extrusion process, processing special metal alloy formula, selects high-purity refined tin, pure lead and high-grade anti-oxidation alloy as raw materials to ensure the high purity of Qiantian brand anti-oxidation solder bar, even if it is used in wave soldering furnace or hand immersion furnace for a long time.

It can effectively control the surface and internal tin content of the metal, avoid a large amount of tin slag, control the tin slag to a small amount, and keep the solder liquid level in the soldering furnace bright as a mirror in the process of wave soldering or manual immersion welding. Our company uses refined tin to make lead solder bar, which has the following unique advantages:

1. The surface of lead 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.

QT-6337T Lead Solder Bar Features
