What is Multilayer PCB?

Any PCB that contains more than two conducting layers is called a Multilayer PCB. These layers are stacked one over the other, and there is an insulating or dielectric medium between them. If you look at a multilayer PCB, it will be just like a double-sided PCB, which means having components on both sides. However, the other layers will be underneath the components.

According to the requirements, the number of layers can be up to 64 layers or even more. All these conducting layers carry a signal, which can be adjusted according to the usage. Therefore, it can be used for complex operations. It offers better performance and reliability.

Structure of a Multilayer PCB

The structure of a multilayer PCB is quite simple. Stack one layer over the other, and there should be a suitable insulating medium, dielectric material, or prepreg to prevent short circuits between layers. In this way, the required number of layers is easily achieved.

The components are placed at the top and the bottom of the PCB, while the inside layers are only for conducting signals, which could be power, ground, and other signals required for the functioning. Therefore, inner layers are also often called routing layers.

Other than that, there are surface finishes, solder masks, and silkscreen at the front layers of the PCB.

How Different Layers of Multilayer PCBs are Connected

The connection of layers in a multilayer PCB is state-of-the-art technology. It is done through different types of vias.

A via is nothing but an electrical connection; however, it is very tiny. It connects the required layers of the PCB, even if they are internal layers. Consider it like a hole that is drilled to connect two or more layers.

There are three common types of vias.

Via Hole Types in PCB

This via is a through-hole from the top layer of the PCB to the bottom. It is like a drill hole, which is plated for conduction. It is usually done to connect all or multiple layers of the PCB.

A blind via is also a hole, but it does not pass through the entire board. It connects one outside layer to the inner layers of the PCB.

Buried Via

A buried via is buried inside the PCB. It connects the internal layers. You cannot see this via.

Advantages of Multilayer PCB

  • Space Saving
    A multilayer PCB saves a lot of space. When layers are stacked one over the other, the overall PCB requires a little space compared to its single-layer or double-layer counterpart.
  • Cheap and Light
    Due to its small size and compact shape, the PCB is quite light. It reduces the overall weight of the final product. Secondly, it is much cheaper than a single-layer PCB offering the same functionality.
  • Durable
    Due to multiple layers of copper and prepreg, the PCB becomes more durable. It can withstand higher temperatures and pressures. Therefore, it is built to last for a long time.
  • More Functionality and Density
    A multilayer PCB can offer better functionality due to its design. Complex operations are sometimes not possible using a single-layer or double-layer PCB, and in such cases, the only option is a multilayer PCB. Secondly, the component density is also higher, which means more components are placed in an area. Both sides of the PCB are used for components.

FAQs about Multilayer PCB

A multilayer PCB is a printed circuit board that has more than two layers of conductive material separated by insulation material. These layers are interconnected by vias that allow electrical signals to pass between the layers.

Multilayer PCBs offer several advantages over single or double-sided PCBs, including higher circuit density, better signal integrity, and reduced electromagnetic interference (EMI).

There is no fixed minimum number of layers for a multilayer PCB. However, most multilayer PCBs typically have at least four layers.

Multilayer PCBs are manufactured using a process called lamination. This involves bonding together multiple layers of copper-clad PCB material with a layer of insulating material in between. The layers are then drilled and plated to create the required circuit patterns.

Blind vias are vias that connect an outer layer of the PCB to an inner layer without passing through the entire board. Buried vias are vias that connect two or more inner layers of the PCB without passing through the outer layers.

Design considerations for multilayer PCBs include proper layer stackup, via placement, and power and ground planes to minimize EMI and signal integrity issues.

A power plane is a layer in a multilayer PCB that is dedicated to carrying power to the various components on the board. It is typically placed adjacent to a ground plane to reduce EMI and improve signal integrity.

A ground plane is a layer in a multilayer PCB that is dedicated to providing a low-impedance ground connection to the various components on the board. It is typically placed adjacent to a power plane to reduce EMI and improve signal integrity.

In a symmetrical layer stackup, the layers are arranged symmetrically around the center layer of the PCB. This results in more uniform electrical characteristics and can be beneficial for high-speed digital applications. In an asymmetrical layer stackup, the layers are arranged asymmetrically around the center layer, which can be more space-efficient but may result in more complex signal routing.
