PCB etching methods generally fall into one ... where a high-power laser is used to ablate copper from the underlying substrate to create traces, or plasma etching, which uses RF energy to ...

Making a PCB is very simple ... one goal is to keep the circuit single sided so you can etch using single sided copper clad. This will allow you to gain some experience before moving on to ...

Three laser ... copper plating, laser-assisted electroplating on stainless steel, and laser-induced chemical liquid phase deposition onto glass. Whoo! I'm using a "20W" 450nm blue laser etching ...
