How to Etch a Printed Circuit Board


Finishing up

There are only two things left to do; first you need to remove the photo layer that’;s still on the copper. Just use some nail polish remover or acetone to remove that layer, when you’;re done the copper should look shinier. Now just drill the holes you need, you can do this with a engraving tool, Dremel, or drill. The most common sizes of drill bits used in PCB’;s are 0.8mm 1mm and 1.5mm so use the right sized bit for the hole you need.

You can leave the PCB clear but it can corrode without any protection, to prevent this apply a soldering agent called flux which you can get this at the local electronics store. When you are finished you can begin placing the components and start soldering.

I hope you’;ve learned from my guide and that you succeeded in making a PCB. And in order to make everything just a bit easier, I’;ve also created a movie so you have a little moving guide to see how the steps go, you can get the movie in 2 flavors.
