Apparently the dielectric between the copper cladding layer and the
aluminium core is only 12um in this product. I think from previous
work that this can raise capacitance into the 400pF/cm^2 range. I had
thought from the previous description that he was using an al-cored
stack-up (fr4 layer insulation).

That should have been 120um.
