Singway Soldering factory has a special hand welding 63a tin rod Sn63Pb37

The lead solder bar produced by Singway is made of Cloud enjoy pure tin ingots with Sn≥99.95 content and electrolytic pure lead metal raw materials. Under strict quality control conditions, the solder bar has full tin degree and high purity without impurities under the detection of our senior engineers using the German direct reading spectrometer. By vacuum deoxygenation treatment, high-tech fully automated production equipment extrusion production, effectively control the degree of oxidation and metal. Non-metallic impurity content.

Product Introduction


Sn63Pb37

Singway uses high-purity Yunnan Tin Electrolysis 1# tin raw material, under strict quality control conditions, through vacuum deoxygenation treatment, uniform casting process, effectively control the degree of oxidation and metal impurity content. Tin has high purity and strong oxidation resistance

The surface of the solder strip is smooth and bright, the liquid surface after melting is bright and the oxidized slag 

residue rarely occurs, which is suitable for various wave soldering, selective welding and manual welding with high wave soldering quality requirements.

DESCRIPTION NOTES: In the same process conditions, the temperature at which the operation takes place is 265℃, while the speed at which the chain moves is 90cm/min. The temperature remains the same, but the original chain speed has increased from 70 cm/min to 90cm/min. Based on the analysis of the principle, this acceleration in chain speed has resulted in improved solder fluidity. As a result, the immersion time is shorter and the temperature of the tin furnace has decreased. Consequently, working at lower temperatures leads to reduced tin slag and less copper corrosion.

Wide range of uses

Widely used in high-grade electronic products or high requirements of electronic, electrical industrial products, smart home, security products LED energy-saving lamps, mobile phones, computer motherboards and other products.


  • Mainly used for reflow welding, wave soldering, hand immersion furnace welding process.
