Comment on DIY PCB making, milling or chemical etching?
moonlight@fedia.io 2 weeks agoYeah I think you would need to get a fiber laser, but it probably wouldn't need much power.
I have heard of using diode lasers to burn off a mask for etching, though.

Yes I’ve tried that as well. It’s way better than messing with toner transfer or those etch resist foils/spray.
It also works well for solder mask. If you apply one white layer and a green layer on top of that you can make decent part labels by lasering away only the green top layer.
