Archive of the former Yahoo!Groups mailing list: Homebrew PCBs

Just had another idea.
How about coating the PCB with a very thin layer of laser printer toner. A powder coating set up would work well for that i.e. uniform electrostatic attraction of the particles to the copper. Then use a laser diode on a CNC mill or flatbed plotter to fuse the resist to the board.
I also thought that powder coat paint might work but it requires a long heat cycle to cure it properly.

It may be time to destroy an old CD burner and try this.

Any thoughts??
