In this section you will only find printed circuits made of FR4 or fiberglass material. The most commercial one has a thickness of 1.6 mm and which has one or two copper layers of 35 µm copper attached. Giving origin to plates that we call 1-sided or 2-sided.
We call these types of plates virgin and they come in different sizes. In order to make a printed circuit or PCB (printed circuit board) there are several methods.
The two most common at the amateur level are: painting with an indelible marker the circuit on one of these virgin plates and later attacking the excess copper with a chemical compound that removes the unpainted part or using a plate that is already photosensitized, which does not it is more than a virgin plate to which a photosensitive emulsion has adhered and through a photographic process we paint our drawing on the emulsion, later we reveal it and then we attack it like virgin plates.
