Definition of Multilayer PCB

A multilayer PCB is a circuit board with more than two layers. Unlike double-sided PCBs, which have only two layers of conductive material, all multilayer PCBs must have at least three layers of conductive material buried in the center of the material.

Structure of Multilayer PCB

Combination of Different Layers

As the name suggests, a multilayer PCB is a combination of different layers. A single-sided PCB and a double-sided PCB combine to form a PCB of this complex design. Multilayer PCBs increase the number of layers and therefore increase the area available for routing. These boards are made by combining two-layer PCBs and separating them with insulating materials such as dielectrics.

Number of Conductive Layers

Conductive layers between insulating materials are a minimum of three, and we can incorporate up to a hundred layers as needed. We treat multilayer PCBs as rigid PCBs because it is difficult to manufacture flexible multilayer PCBs. Most of our common multilayer PCBs consist of 4 ل 8 طبقات. Smartphones can contain up to 12 layers as they suit the complexity of the application. Manufacturers prefer even-numbered layers to odd-numbered layers, because laminating odd-numbered layers can make the circuit overly complex and problematic, and high cost is also a factor to consider.

Advantages of Multilayer PCB

Multilayer PCBs have some advantages over single or double layer PCBs. They have higher densities, allowing for greater functionality, capacity and speed. Electromagnetic shielding is easier if the power and ground planes are placed correctly. No extensive wiring is required, so it is lightweight. They reduce size and help save space. They are more flexible than other types of PCBs.
