A printed circuit board combines the functions of a carrier of radio elements and the electrical connection of such elements. The transition to printed circuit boards marked a quantum leap in the field of designing electronic equipment. To install the components and connect them to the conductors, additional elements are used: contact pads, transition metallized and mounting holes, connector lamellas, sections for heat removal, shielding and current-carrying surfaces, etc. The dielectric base and conductors are elements necessary and sufficient for the printed circuit board to be a printed circuit board. The main structural elements of a printed circuit board are a dielectric base (rigid or flexible) on the surface of which the conductors are located.
PCB board:A printed circuit board refers to the design of fixed electrical interconnects on an insulating base. PCB board -printed circuit board) is an electrically insulating material (getinax, textolite, fiberglass and other similar dielectrics), which is thinly coated with conductive thin plates (printed conductors) on its surface and has contact pads for connection and installation Radio components, including modules and integrated circuits.
