Product Introduction
Sn30Pb70 solder wire is a common lead solder wire alloy with a low melting point of about 183 ° C, which makes the welding process easier to control and operate, helping to improve welding efficiency and reduce energy consumption. Moreover, it has good wettability, which can effectively wet the welding surface and form a uniform weld, which helps to improve the quality and reliability of welding. It also has good electrical conductivity and is suitable for welding applications requiring good electrical conductivity, such as electronic component welding and circuit board connection. And in the welding process can provide reliable welding performance, form a strong solder joint, with good mechanical strength and electrical properties. It is widely used in electronics, electrical appliances, communications and other fields.
The lead solder wire can be adapted to various welding processes and conditions. It is suitable for manual welding, automatic welding and wave welding and other welding methods.
