Step 5 Laser

Put the exported file into your favorite laser program, in this case Illustrator, and make sure that the size is correct and everything is looking fine. After that it is time to send it to the laser. The settings I use to etch the spraypaint away is the Marble setting on my Epilog 40 w laser. This will change depending on your laser type.

I have been building my own electronic equipment since I needed a selection of punches for the tube sockets. Do I need to get a laser engraving tool now?

I'm missing a stage here. How did you get the printed schema onto the coated PCB? Does it have to do any thing with the paint? O>

The paint just shields the copper from the acid. What he actually did was use a laser cutter to remove the paint, essentially drawing the circuit in spray paint. Seems like a really great method, if you happen to have a laser engraver laying around (don't we all have one of those?). But you can use another method for this, like toner transfer.
