I have a partly-baked idea for improving temperature controllers, but it

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

I'm attempting to throw money at the problem, hopefully in the direction
of somebody who's done it many times before. *That way I can get on with
the parts I'm not sure will work!

A thermal Faraday shield sounds like some sort of distributed heating
(cooling?) Can you mock something up, by soldering together bits of
nickel wire? (I like phosphur bronze for heaters.)
