Homebrew PCBs

Hey, I was going to call you that ;-)

I haven't got the electron microscope out, but I believe the layer of  
plastic is topped with some sizing. It's certainly sticky on top, and  
certainly not water soluble which is why you have to reasonably  
vigourously toothbrush the whole affair once you've soaked the paper  
off (it's pretty brittle once you've got the paper away).

It could be molybdenum, it cold be ectoplasm, but there's *something*  
coating the best paper I've used, and it's insoluble, thin, and toner  
cannot pass through it onto the wood fibres.
