What is a Multilayer PCB?
A multilayer PCB is a circuit board that has more than two layers (top and bottom surface). Unlike a Double-Sided PCB which only has two conductive layers of material, a multilayer PCB can have multiple layers of material stacked and sandwiched between the top and bottom layer.

The Manufacturing Process
The manufacturing process of multilayer PCBs involves several steps, including designing, etching, drilling, plating, and testing. The process begins with the design of the PCB, which is done using specialized software. The design is then transferred onto a copper-clad board through a process called etching. Drilling is done to create holes for mounting components. Plating is the process of adding a thin layer of metal to the drilled holes to ensure proper electrical connection. Finally, the PCBs are tested for functionality.

Applications of Multilayer PCBs
Multilayer PCBs are used in a wide range of applications, including computers, telecommunications, industrial controls, and medical equipment. They are also used in the automotive, aerospace, and defense industries.

Advantages and Disadvantages
While multilayer PCBs offer several advantages such as high density and improved performance, they also pose certain challenges. The manufacturing process is complex and requires a high level of precision. Moreover, the cost of multilayer PCBs is higher due to the increased number of layers and the complexity of the manufacturing process.

Conclusion
Multilayer PCBs play a vital role in the electronics industry, providing the necessary components for various applications. Despite the challenges, the advantages offered by multilayer PCBs make them an indispensable part of modern electronic devices.
