On the PCB advantage

A printed circuit board or circuit board, high frequency PCB there are several advantages of the older way of building electronic. In the past, the components of an electronic device within a large wire connection, and placed anywhere, they can adapt. As you can see in this 1948 television screen, this method "chaotic", and use a lot of space.
The printed circuit board using a different method. Components are installed in a non-conductive plates, known as the small pathway to connect the "traces." Because they are usually designed on the computer, printed circuit boards for many of the components in the smallest space.

Parts of the PCB

When the printed circuit board traces, easily noticeable. These thin conductive and connected in the circuit components. They replace the wire is much greater in the past.
There are many holes on the PCB. These are precisely drilled for each component needs to be placed. For example, if part of the circuitry of a chip, you need eight connections, the same number of holes on the board. In this way, part of the electronic circuit can be installed completely flush, no long wires or wiring. professional PCB assembly again, this saves a lot of space.
Added to the PCB, the last part of the component itself. Electrical equipment unit must contact Common components, including chips, diodes, resistors and switches. Components of the implementation of the "working" the circuit, printed circuit board connection.

Create PCB

Today, the vast majority of electronic circuit design on the computer. This makes the parts created before the electronic engineers to perfect arrangements to enable the design permanent.
Much like ink on paper, polychlorinated biphenyls (PCBs), literally means "Indian" when ready. An original board has two, both top and bottom of the non-conductive metal such as copper table. Anti-etching ink printing requirements on the design of the metal layer. Board, and then use chemical etching. This eliminates the metal layer, in addition to the printed design. The result: a conductive traces remain in the circuit mode.
Once the components are connected and soldered to the board, PCB testing, and shipping. The whole process normally fully automated, printed circuit board with thousands or millions are all over the world the same circuit board manufacturing.
