[0002] Tinned copper refers to copper with a thin layer of metallic tin plated on its surface, such as tinned copper wire. Tin forms a thin film of tin dioxide in the air to prevent further oxidation, and tin can also form a similar film with halogens. Thus, it has both good corrosion resistance, certain strength and hardness, good formability and easy weldability. The tin layer is non-toxic and odorless, can prevent iron from dissolving into the packaged goods, and has a bright surface;

[0003] In the prior art, generally, copper wire is introduced into a copper wire tin plating furnace through guide rollers, and the tin liquid in the furnace is used to tin plate the copper wire.
