PCB application in electronics

A printed circuit board is the basis of any electronic product, being part of computers, cell phones and military equipment. Appearing more than 100 years ago, this small device marked a huge leap in the development of electronic equipment. Now printed circuit boards, almost as the basis of electronic equipment, are part of computers, cell phones and military equipment.
The use of printed circuit boards in electronics made it possible to reduce the mass of devices by an order of magnitude and increased the density of the layout of circuits, which ultimately reduced the cost of equipment and simplified their manufacture.
As you know, such materials as fiberglass, getinaks, and ceramics are most often used as the basis of a PCB design. Also, the base of printed circuit boards can be a metal base coated with a dielectric (for example, anodized aluminum), and copper foil of the tracks is applied over the dielectric.
A single-sided printed circuit board is a plate on one side of which is printed conductors. In double-sided printed circuit boards, conductors also occupied the wrong side of this plate.
The transition from single-sided printed circuit boards to double-sided was the first step on the path from plane to volume. The final transition to volume occurred with the advent of multilayer printed circuit boards. Today, many companies produce multilayer printed circuit boards containing up to 28 layers.
Such printed circuit boards made it possible, first of all, to miniaturize the electronics. Aerospace technology, aviation, computers, as well as rocket systems and weapons quickly took advantage of this space preservation.

Transition to the micro level

The increasing miniaturization of electronic devices also required the transition of printed circuit boards to the micro level.

The PCB Manufacturing already in areas like nano-technology makes any of the most unrealistic forecasts regarding the development of an electronic base quite realistic. We can talk not just about micro, but even about nano-miniaturization of printed circuit boards. Already today, individual elements of printed circuit boards are on the approaches to nanometers.
