I have a partly-baked idea for improving temperature controllers, but it
requires a bunch of nickel plated polyimide film--say 3 to 8 mils thick,
with 40 microinches of electroless nickel on it.

So, plate your nickel onto anything you want, then apply/bake the
polyimide as a conformal coating, and etch away the 'anything'
layer?
