Print it out onto some semi glossy photo paper. Then quickly take this paper, cut out your design and place it face down onto some blank PCB board. Then use an iron and press the design on to the board.
Then quickly take this paper, cut out your design and place it face down onto some blank PCB board. Then use an iron and press the design on to the board. Use A LOT of pressure and ensure all parts of the design make good contact with the blank PCB. Keep it pressed for at least 5 mins. I have found that having steam on/off makes no difference.Then take your blank PCB with the design stuck on to it and soak it in soapy water for about 20 mins to loosen the paper. Then CAREFULLY remove the paper. Be sure not to remove any of the black ink traces beceause these are what stops the acid in the etching process. I use a kind of rubbing motion to remove the paper. Keep it wet all the time so that it seoarates easily from the copper board.

Done and ready for etching: Get some etchant and just follow the instructions for the dilution level. I just use a noral ceremic or glass bowel. Ghetto style. Add boiling water from a jug: And slowly swirl or rock the bowl around. The liquid must be always moving over the copper board to get it to etch properly. Done! Now scrub the black ink off the PCB and voila, you have a custom designed PCB: Then all you need to do is drill out the holes and start mounting the components: It will take maybe a couple of tries to get the hang of it but once you’ve got it you can produce perfect PCBs everytime.
