The fundamentals of PCB manufacturing explained

A printed circuit board is one of the most commonly used components in electrical and electronic devices today. As the name implies, this particular variety of circuit boards consists of printed or recorded circuits instead of real cables that extend from one place to another.

Because the circuit is really ‘printed’, the plate becomes very compact. Although condensed, it can carry very complex circuits that can be kept in several different layers. That is the exact reason why I would hear the terms “three-tier board” or “eight levels” in the PCB manufacturing industry.

Some steps must be done before all the PCB can take shape. The process of manufacturing a PCB begins with the design. Special software is used to design the circuits that would eventually be printed on the PCB. This software, together with the electronic design automation tools, helps to design the circuits for a multilayer or single layer PCB.

The design of the PCB is based on the dimensions of the laminate in which the circuit must be placed. Once the design is finished, the impedance of the line is determined, the placement of the components is finished and the tracking of the signal is routed.
