Familiarity with types of electronic boards; Which type of fiber is right for you?
You can find all kinds of electronic boards in most equipment around you by looking around. These devices have led to increased comfort and facilitation of our daily life. The ever-increasing expansion of this equipment has led to the acceptance of this type of products by manufacturers of various industries. If you also intend to enter this field; It is better to have enough information about the types of electronic boards. In this article, we are going to briefly introduce you to the types of electronic boards and the use of each one.
Types of electronic boards
Every electronic board consists of a raw board (printed circuit board or pcb) on which the components are assembled. The raw board is called printed circuit board or pcb. Each electronic board has different types due to its features. Copper traces on each board connect the parts to each other. These cracks are one of the factors that can make the design of each circuit different. But what we are looking for as difference; The difference is in the type of pcb. In the following, we will describe the types of pcb.
# Classification of types of electronic boards based on the number of layers;
Single layer PCB (micro)
Single-layer pcb is simpler and less expensive than other models. Single-layer PCBs are made of only one layer of copper
In a single-sided fiber PCB, all components are assembled on one side of the board. This type of board is used to produce simple electronic devices. in terms of cost; This type of pcb has the lowest price among other types. Single-sided boards are produced with different materials, such as bone board, aluminum board, fiberglass, CEM, etc.
double layer pcb (double)
In this type of pcb, the copper layer is located on both sides of the board, as a result, it is possible to assemble parts on both sides of the board. Double-layer boards are used in most advanced electronic devices due to their features. In this printed circuit board fiber connection, the two sides of the board can be connected through metallized holes. As a result, these boards create more space for arranging parts.
Multilayer Pcb
This type of pcb consists of several conductive layers, all layers are connected to each other through the holes on the board. SMD and DIP components can be on any layer of the board. These types of boards are more expensive than other types of electronic boards. One of the most important advantages of this type is the possibility of reducing the board size to the desired size, which leads to occupying the least possible space. Usually, due to the high complexity of this type of electronic board, their use is only in more advanced devices.
Classification of types of electronic board based on fiber type;
hard pcb
Electronic boards differ not only in terms of the number of layers, but also in terms of materials. Rigid pcbs have more strength due to their inflexibility and are widely used in products with high vibration.
This type of electronic board has different materials such as fiberglass (FR4), bone, semi-fiber (CEM), and metal boards such as aluminum.
Flexible pcb
Flexible boards are composed of a combination of fiberglass and circular wires. These types of boards are produced using photolithography technology. In cases where boards need to be installed in a small space and at different heights in one place, flexible boards with high flexibility can easily change shape. Flex PCBs are made of a polymer insulating layer and only smd components are mounted on them. The most important advantage of these boards is their light weight and flexibility, which you can easily use in all electronic equipment, and their biggest disadvantage is the high price of their production.
Pcb rigid_flexible
These types of boards include both hard and flexible types that are connected to the monolayer as double or multilayer. These types of boards are mostly used in military equipment due to the small space they occupy. Although the production process of this model of boards is very complicated, they are used in terms of practicality.
