Product Introduction
Sn55Pb45 lead solder wire is made of Yunnan pure tin ingots and pure lead. Under strict quality control conditions, after vacuum deoxidation treatment, to ensure the purity and uniformity of lead solder wire. This lead solder wire has the following characteristics:
First, high oxidation: After vacuum deoxidation treatment, the oxidation degree of Sn55Pb45 lead solder wire is low. This helps to reduce the formation of oxides and improve welding quality and reliability.
Second, low residue: Sn55Pb45 lead solder wire is carefully controlled during the manufacturing process to reduce the content of impurities and residues. This helps to reduce pollution and adverse phenomena in the welding process and improve the quality of welding.
Third, uniform casting: Sn55Pb45 lead solder wire is uniformly cast during the manufacturing process to ensure that the ratio of lead and tin is evenly distributed. This helps to improve welding quality and stability.
