dry etching generally refers to methods like laser etching, where a high-power laser is used to ablate copper from the underlying substrate to create traces, or plasma etching, which uses RF ...

Three laser experiments today: laser-induced electroless copper plating, laser-assisted electroplating on stainless steel, ...

Etch resist and toner transfer ... (yet), printing PCBs with a laser shows a lot of potential. Check out a video of [reonarudo]’s bot burning some copper after the break.

Copper’s optical absorption of blue light ... The thickness and composition of the layers, and the size and shape of the laser etching, can all be chosen to determine the laser’s properties ...
