Couché paper sheets 80gr, although they can also be replaced by magazine sheets of the same thickness.
Printed circuit board.
Ferric Chloride. (Be very careful about where we dispose of it, it is very toxic)

Plastic tweezers.
Aqua compressor.
Aquarium air diffuser.
Laser printer.

Second part of this double post to learn how to make a printed circuit board, it's quite simple.
steps that we must strictly follow for the result to be professional and to avoid various problems,
I also take advantage of this post for the third part of themetal detector, in which we will have to do the
plate of the same.
Assembly:
First of all, we need to have the sketch designed, if you don't know how to do it,hereyou will be able to find
the program I use to create designs is very simple and intuitive, you have to print that sketch
on the coated paper with the laser printer. When printing, be very careful about which side
Go ahead, you know, the mirror effect.
2- Next, we get to work on preparing the plate, we take the steel wool,
we smooth the entire surface of the plate until it is completely polished and then we file the edges of
the plate, as shown in the image.
3- Now it's time to iron the sketch printed on the couche paper onto the plate, we place the couche paper.
on top of the plate as shown in the image and we iron it as if it were a t-shirt, we need to
be very careful not to give it too much heat, the tracks could warp. To know if what
You should check one of the corners, when it is glued, you must wait for it to cool down, that when
touching it, we won't burn, (this point is very important) when you have checked it, it will be ready for the
next step.
4- This step doesn't have much of a story, the only thing we need to do is immerse the plate in hot water.
to peel off the paper and not the ink. When we put it in, we will gradually scratch off the paper that comes off.
weakening, be very careful not to pull or you will bring the tracks with you. Afterwards, we will cut the plate.
the edges.
5- Now we will start with the chemical attack, first we will fill the jar with ClFe (Ferric Chloride) of
water and we wait until the little balls dissolve, then fill the container (Tupperware) where we will attack the
plate. We place the aquarium diffuser connected to the compressor with a tube at the bottom of that container.
silicone, it is also advisable to heat the solution in a water bath. In about five to ten minutes the plate
It will be ready, in any case, you should keep an eye on it to prevent it from eating more copper on one side than the other.
Another, you can help yourself with the plastic clamp.
6- When you see that all the copper that should have been eaten is gone, we take out the plate, and we put it in water to
remove the remnants of ClFe, and with a cloth and solvent, we remove the ink residues that remain attached.
Next, we will make the holes for the pads using a dremel or small drill.
With this, we will have our printed circuit board ready, the next step would be to solder the
components, but that does not need an explanation.
