Macetech shares some fast action footage from his PCB fabbing process –
This is a video running at 4X speed, illustrating the etching process I’m using. The paint is removed from the copper-clad PCB in an Epilog laser cutter. After a wipedown with alcohol to remove any paint dust, the PCB is etched in ferric chloride solution.
HOW TO – Use a laser to etch PCBs (printed circuit boards)
