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.

I need to pattern it and then solder to it. Copper is too conductive,
which is a pity, since I already have a roll of polyimide with 1/2 oz Cu
on it.

I haven't found anybody that's interested in supplying it in engineering
quantities (say 10 square feet).

Anyone here have a favourite shop that does nickel plating on plastic?

Thanks

....alternate..vacuum sputter deposit for any thickness you want; control
can be as good as 1/10 wavelength of light (pick your favorite color).
....another alternate..perhaps gold film?
