The significance of copper tin processing: tin can prevent copper exposure in the air and be oxidized to form a layer of film - patina! It's CU2(OH), 2CO3. And the patina's poor electrical conductivity will increase resistance.
The significance of copper tin processing: the resistance of copper can not be larger than tin ~ copper resistivity is 1.7×10-8 copper resistivity is 2.2×10-7 copper resistance is much larger than copper, in fact, tin is mainly to prevent copper oxidation.
The significance of copper tin plating processing: tin coating has better stability in the air, two different metal materials in a variety of ambient temperatures to achieve permanent atomic intercrystal bonding, and copper tin plating, zinc layer distribution is uniform.
