Does the tinning-coating replace where copper would have been in
the overall wire and tinning is of higher reistence?
Is flexibility affected?
Tin has a much lower conductivity than copper, and as RF travels on
the surface of a conductor, it would attenuate RF and high frequency AC
So how high does the frequency have to be for skin effect to matter?
