In multiplayer PCBs, few layers might be assigned with fixed tasks and are termed as planes i.e.

In Multilayer PCB, outer layers(top & bottom) are single-sided PCBs, while the inner layers are double-sided PCBs.A Multilayer PCB has an Inner Layer Core present at the center of all the layers and coated with a Copper layer from both sides, while layers of prepreg(woven glass cloth with epoxy resin) are used for insulation.A PCB is called Multilayer PCB, if it has 3 or more layers(sheets) of copper foil, insulated from each other(by lamination or coating) and joined together to form a single piece.I hope you understood the basic concept of MultiLayer PCB, now let’s have a look at the proper definition of Multilayer PCB: Multilayer PCB Definition So, any PCB having 3 or more layers is termed a MultiLayer PCB. So, to overcome this issue, Multilayer PCBs are introduced, where connections/wirings are split across different PCB boards(called layers) and these layers are laminated to keep insulated from each other and glued together. So, now when SMD components are used in PCBs, they are placed very close to each other, and in complex designs, there’s not enough space to pass the tracing lines of connection wires. SMD components are very small-sized components and their sole purpose is to reduce the overall size of electronic kits/circuits. But with the research in nanotechnology, electronics get introduced with SMD(Service Mount Device) components. Initially, electronic components were available in DIP packages only and PCB boards were used to be large-sized, thus having more space for the PCB wirings/connections. So, let’s get started with What is MultiLayer PCB? You should also have a look at the JLCPCB Multilayer Fabrication services. Let’s first have a look at the definition of PCB: PCB is an abbreviation of the printed circuit board, comes with different copper conductive paths, traces & lines, incorporated on a single board to electrically connect different electronic components. We have seen single-sided PCB and double-sided PCB in our previous posts, so go through them first. Today, I am going to give you a detailed overview of Multilayer PCB, where we will cover what is Multilayer PCB? & why do we need to use it? We will also discuss its Construction, advantages, disadvantages, etc.
