DIY transfert/etching PCBs at home

dashie Electronics January 29, 2021

For a new project I am starting I needed to do DIY PCB using the transfert and etching method.

I got a ~cheap laminator off amazon (a metal one, which was more expensive than an all-plastic but it seemed more rugged and probably more able to reach 200’C), a few litters of Ferric Chloride, cheap photo paper and tried it.

The layout was printed in mirror on cheap photo paper for laser and printed on my old laser printer.
cleaning under water done, track was fixed later, paper residues on the tracks isn’t an issue.
The magic solution.

Forbidden coffee, the PCB is actually swimming in it.

After ~30 minutes, the PCB has been cleaned under water, and looks perfect !
