Why does tin plating have good solder wetting properties?

Q: Why does tin plating have good solder wetting properties? A: Tin, the metal used in tin plating, has a low melting point of 231.9 degrees Celsius and is also a component metal of solder, allowing it to blend well with molten solder. Even if there is an oxide film on the plating surface, it is soft and easily broken, which means it has little impact on solder wetting properties.
