Talk:Printed circuit board

I overhauled and added a ton of info about PCB design to the document, I also nominate the last section "HV Construction techniques" for deletion as it isn't as relevant with the other information summarized.

Also, anyone with knowledge about RF PCB design should add a section under design criteria.

I'll eventually flesh out the chemical etchant section and write a separate chemistry page on FeCl3 and CuCl2 etchant chemistry.
