Those involved in PCB board manufacturing make printed circuits, i.e. electronic supports designed to connect and interconnect the electronic components of a circuit through conductive tracks engraved on non-conductive material.
Most PCB boards are made of copper-plated vetronite, which is fiberglass covered with a thin metal layer. Through the photoengraving technique, that is the action of light and acids, or metal milling, this layer is carved. The result is the creation of PCB boards with tracks that will connect the components of the designed circuit together.
A printed circuit board or PCB will therefore contain all the components of the designed electronic circuit which will be soldered onto it.
PCB board creation: the functions
PCB or printed circuit boards serve several functions, including:
- electrical connection between electronic components to build a real electrical circuit;
- mechanical support for components and accessories in order to create a system that allows the printed circuit to be housed even in complex-shaped containers;
- direct creation of passive electronic components, for example for the creation of capacitors and inductors capable of exploiting the parasitic capacitance between the layers and the desired geometry of the tracks.
Finally, when talking about the creation of PCB boards it is important to identify the types of printed circuit, which is defined mechanically:
- rigid-flexible, i.e. with rigid parts connected to each other by flexible sections.
