Do you mean the 'press and peel' resist film?
You print your pc layout on the film using a laser
printer or copy machine and then iron the film on
to the pc board. The toner becomes the resist, and
you then etch the board in the usual manor.
You can buy the stuff from www.techniks.com

I think this is the stuff. Let me get this straight. It's actually the
toner from your laser printer which transfers to the copper on the
board. The toner is the resist. Is that correct?

Thanks
