The printed circuit board is one of the constructive elements of any modern electronic device. First of all it is intended for mechanical fixing and electrical connection of the components of electrical circuits of the electronic device.
Structurally, the printed circuit board is a plate made of dielectric material (in most cases, but it is also possible to use structures on an aluminum substrate to improve the heat dissipation) with electrical circuits formed on its surface and volume.
The development of printed circuit boards is a process of mechanical and electrical design. During the development of the printed circuit board, the electrical components are connected by conductive circuits, but the process of connecting the components is in fact one of the most recent stages of the board design and is usually denoted by the term PCB tracing.
Initially, it is required to conduct an analysis and the possibility of placing the components of the electrical circuit on the board surfaces in specified dimensions, which are usually determined by the design features of the entire product and in particular the product body.
At the end of the placement phase, the electrical elements are combined. In the process of connecting electrical components, it is necessary to take into account a number of parameters, such as the amperage, the impedance, the influence of neighboring electrical circuits, etc.
