Electroplating for electronics
The normal process now is a destructive one, where unwanted copper is etched away.
What about figuring a way to electroplate the traces onto a substrate? Various toys and model parts are made of plastic, and yet have been electroplated with a cheap form of chrome. Why not apply that to PC boards?
I'm thinking that a photographically negative mask could be used in a photo-sensitive process to apply the conductive surface to a heat resistant substrate, and then the copper traces could be electroplated on.
Anyone have any thoughts on this, primarily at a hobbyist level?
