What are the different types of printed circuit boards?

The printed circuit boards are an independent base for the maintenance of electrical components used in all types of devices, from computer systems to radars, radios and household appliances. There is a great variation in the PCB assembly that vary from simple to complex.

These are some of the main types of printed circuit boards:

On one side

Single-sided plates are the least complex. They are built with all electrical parts attached to one side of the base material with the other coated with traces of copper. Copper is the preferred type of metal because it is a very effective electrical conductor. In addition, the thin layer of copper can be covered with a welding mask to provide long-term protection. This plate is the preferred one for the most basic electronic items and, often, the first type of table that the amateur uses at home. Although they are the most economical to manufacture, they are not the most used due to design and use limitations.

Double side

Double faceplates are the most typical option and are constructed with components and parts mounted on both sides of the base material. This type of plate is designed with many holes to allow the connection of the circuits on each side. There are two main types of connection methods that include surface mount technology and through hole technology. Surface mounting technology is the most complex and depends on the welding of small cables on the board. This is the most efficient option and creates the lightweight table with great speed and ability to perform multiple functions. The technology of step is a little less efficient and is based on the passage of small cables through the holes of the plate to connect the different components.

Multi layers

Multilayer boards are composed of several base materials that are separated by a small separation area. The most common sizes include 4, 6, 8 and 10 layers. However, it is possible to manufacture very large tables with a total of 42 layers or more. This type of card is the preferred option for highly complex electronic circuits.

Rigid or flexible

In addition to the difference in usable sides and layers, the printed circuit boards may also vary in relation to their stiffness. The most typical type is the fiberglass base that is totally rigid and does not offer flexibility in movement. However, there are also flexible plates in a plastic material that are intended for spaces that are inaccessible to rigid alternatives.
