There are a lot of methods to etch your own circuit boards, and with that comes a lot of different tutorials. I'm not going to try and reinvent the wheel here, and this probably won't be a comprehensive list, but I thought it might be helpful to some to have some examples of DIY etching.
First is the Press 'n Peel method. Steve Daniels of Small Bear Electronics has written a great tutorial on this method, and it's the method I typically use when etching my own boards.

Steve also wrote another tutorial for making a PCB using the Positive Photo Method.

Lastly (for now anyway), is a tutorial by my friend Cody Deschenes. The method is similar to the first tutorial link, but instead of Press 'n Peel paper (which can get pricey), Cody uses much more affordable photo paper for transferring the toner to the copper clad board.

And if you don't like reading (which probably means, you haven't made it to the end of this post and won't be reading the following anyway) there are numerous tutorials on YouTube using these and other methods to etch your own boards.

I've watched a ton of YouTube tutorials and here are a couple that I liked a lot. The first is from The Ben Heck Show (you should watch some of his other videos, this guy is awesome). He shows how to etch using a method like Cody's photo paper method, as well as using a laser to create the etchant mask or hand drawing it with a marker.
The second video is from another cool YouTube channel, Make. This tutorial shows how to make a PCB using the positive photo method.
Update March 8, 2017:
Here's a quick little tutorial I did a while ago on Instagram showing how I use yellow heat transfer paper to transfer toner.
Thanks bro!
ReplyDeleteThe best way to do at home is the photopaper (glossy paper) laser printed. The result is fantastic. I'll post a photo.
Thanks !!! =) for all !!!
ReplyDeleteThe PCB etching process is an exothermic reaction, it generates heat.
ReplyDeleteI use the press and peel sheets and etch using the peroxide/vinegar/salt method. Works great
ReplyDeleteRobotmeister, do you have the portions for that peroxide/vinegar/salt method? Its very interesting.
ReplyDelete100 ml of peroxide
Delete30 grams of citric acid
5 grams of salt
The best method is to heat the peroxide first, then add acid and salt and mix it well.
Hi, how long do you leave the PCB in the solution?
DeleteHi have you tried?
DeleteI use such method (peroxide+salt+citric acid) for about a year. Works perfectly.
DeleteTime may differ depending on amount of traces and circuit size. Usually not longer than 15-20 minutes

ReplyDeleteI don't have a laser printer :'(
ReplyDeleteyo no tengo ni papel especial ,,ni impresora x lo pronto dibujo todo el circuito a mano con plumon indeleble y luego el conducto regular ,,vierto el acido ferrico a la placa y listo ,,esto mientras mas adelante compre impresora laser y otros, hay que ingeniarsela nomas.
ReplyDeleteHi there I was just wondering how easy is it to convert the PDF plans to work with a CNC machine
ReplyDeleteReally easy!!
DeleteHCl-2
ReplyDeleteH2O2-1
H2O-5
A bit late to the game here, sorry. I've bypassed the transfer/etching process completely and have made a few PCBs using the images on this blog and a desktop CNC. You just need to flip the image and convert it to a vector. The CNC software does most of the rest.
ReplyDeleteThank you for this insightful post on PCB etching, a critical step in the PCB manufacturing process that often doesn't get the spotlight it deserves. Your comprehensive overview sheds light on the intricacies of etching, highlighting its significance in defining the precision and functionality of the final circuit board.
