PCB Functions
The role of the PCB is to support the electronic components and to ensure the electrical connections necessary for the operation of the system.
PCB cannot perform these functions alone, soldering is necessary to make the mechanical and electrical connections between the components and the tracks of the circuit.
From calculators and microwave ovens to cell phones and aircraft control systems, all electronic equipment used today involves the use of PCBs. These devices are printed circuit boards. Its purpose is, in a simplified way, to connect electrical components in an organized manner, since the logic that your circuit must exercise is already defined.
Planning is the keyword that defines the production of a PCB since its entire creation process is methodical. There is basically an exchange of debugging troubleshooting of your circuit for the previous logical organization of its components. That is, it is necessary to think very carefully about the connections and functions of each of the elements of your circuit before making it, with this, it is possible to not have problems of bad contact in the wiring.
