Advantages of embedded components
The first, but not the main, advantage is obvious –components are enclosed inside PCB.
Consequently, the external stress affects it less since it is distributed evenly throughout the structure. Note that the position of embedded components falls to the structure center, so it is less deformed when bending the PCB cavity.
But the main feature is the compactness and location directly inside the PCB layers. This frees up additional space for the use of large and/or other components.
There are two types of components: passive and active. The first are resistors and capacitors. They are located inside the PCB layers, thereby freeing up space for active components on PCB. Active components are transistors, integrated circuits, logic gates and others.
