We make a printed circuit board using a laser engraver

There was no laser printer and iron, but there was a laser machine, so our Ilya Makarov tried out a new technology (at least for us it is new).

The main difference from the classic LUT is that it is not necessary to transfer the paper itself and the very low probability of marriage on paper.

Generally:
- Cut off a piece of PCB
- we cleaned of fat
- We cover copper with matt black paint
- Let dry
- At this time, you need to prepare a file for engraving (did export from Eagle; put a large resolution (dpi) and format .tif)
- I made an engraving on a laser machine (on our 40w CO2 laser I set a speed of 150mm / s and a power of 20%). Made two runs.
')
Well, then everything is as usual.
- we weed
- remove paint
