to repeat martin brown, try a bowl of electroless nickel. If you're not
familiar with the technique, maybe google.

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
