I think you are best off having this made somewhere, unless you can
find the 105u base material and just need to etch it.
It will be difficult to find because board houses will start with
thinner stock and plate it up, so surplus is rare.
Tin has lower conductivity than copper, so it would not do the same.
With very high frequency circuits plating can actually increase
overall resistance because the skin effect pushes half the current
into the low conductivity plating.
