Multilayer PCBs are costlier than single side or double side units, so why are they used so widely?
Although the unique cost is higher, the overall final cost is not. Indeed, if we consider the essential elements such as the electronic functionality, the larger component area available, and the lighter weight, the multilayer printed circuits provide a complete solution.
All these improvements and benefits allow us to predict that Multilayers PCBs will continue to be the best choice
What is Multilayer PCB?
PCBs can be single-sided (one copper layer), double-sided (two copper layers on both sides of one substrate layer), or multilayer (outer and inner layers of copper, alternating with layers of substrate).
Multilayer PCBs allow for much higher component density because circuits on the inner layers would otherwise take up surface space between components. However, Multilayer PCBs make the repair, analysis, and field modification of circuits much more difficult and usually impractical.

Do you need Multilayer PCBs?
The Multilayer PCB is mainly used in professional electronic equipment, such as computers and military equipment. The Multilayer PCB is also very useful in high-speed circuits.
The Multilayer PCB can provide more space for the conductor pattern and power on the inner layers. The technology can be a solution for shielding trouble, impedance, and high-speed signal application.
