Singway Soldering Factory Environmental protection solder bar Lead-free solder rod Sn99.3Cu0.7

Product Introduction

The lead-free solder bar produced by our company is made of high purity Yunnan tin gold raw material mixed with electrolytic copper and die-cast in a large vacuum extruder. The surface of the solder strip is silver and bright, and it is easy to solder various electronic products.

1. High purity raw materials: high purity Yunnan tin gold raw materials are mixed with electrolytic copper to ensure stable quality and high purity of the solder bar.

2. Vacuum extrusion process: The use of large vacuum extruder die-casting, to ensure the uniformity and consistency of the solder strip, improve product quality and performance.

3. Silver and bright surface: The surface of the solder bar is silver and bright, beautiful and generous, which is conducive to visual inspection and operation in the welding process.

Singway's solder bars are manufactured using vacuum continuous casting, which removes contaminants from the solder and reduces the oxygen content of the tin bars. The result is a solder product with higher purity, less tin residue and superior reliability.

Product Features

When the chain speed was increased from 70cm/min to 90cm/min, a significant difference appeared. First of all, the fluidity of the solder is significantly improved, so that the solder covers the solder joint more evenly, improving the welding quality. Secondly, the residence time of the solder on the welding surface is shortened, which reduces the chance of oxidation and ensures the reliability of the solder joint. At the same time, due to the increased fluidity of the solder, the temperature of the tin furnace can be lower, reducing the formation of tin slag, which helps to maintain a clean welding environment. In addition, the reduction in welding time increases the production speed and reduces the use of energy and materials, thus reducing costs. Overall, increasing chain speed improves many aspects of the welding process, improving quality, efficiency, and reducing costs.

Applicable to the industry

Widely used in precision electronic instruments, precision medical equipment, high-end electronic products, automotive electronics and other products manual dip welding and wave soldering; After adding a trace amount of precious metal elements to match, the developed solder bar products are also suitable for manual dip welding and wave soldering of electronic component feet, wire materials, PCB plates and other products.
