Comment on PCB etched with toner transfer method

Nicely done. I have given up on toner transfer and instead use a laser attached to a 3D printer to burn away spraypaint.
Alignment on double sided boards is difficult though.

Interesting, how much power does the laser have to need to be able to burn the paint?

I’m using a 10W laser at about 25% of its power. It’s a 450nm laser that is sold as 80W electrical power on AliExpress but Chinese webshops often exaggerate their specs.
