What are the Different Types of PCBs?

A printed Circuit Board is the base for all the electronic components in any electronic device. It is a non-conductive surface sandwiched between one or two layers of copper plates that further connect different components. The circuit board’s layout changes make the device more receptive, fast, and efficient. pcb company are the real mastermind behind creating better gadgets.

PCB comes in different types specified for different devices and purposes. Let us understand their types and purpose. They are made of different materials, layouts, and precision. Some of the PCB Types are listed below.

Single Layer PCB

It is the simplest PCB and necessary form of PCB designing. They have one layer of non-conductive substrate and one layer of copper where the connections happen.

Double Layer PCB

As the name suggests, the double layers have two copper layers connected to the non-conductive substrate on either side. It is connected through plated holes in the substrate connected to pad pads in the circuit boards.

Multi-layer PCB

These have multiple layers of copper plates over the substrate plate. The most advanced board has up to 40 layers, but the commonly used ones have only up to 8 layers.

High-Density Interconnect PCB

These pack multiple layers and functionalities in a much smaller space using laser-drilled microvias, laminates, and fine lines. Reduction in size of the gadgets has been possible due to these miniaturized boards.


These are the four major types of PCBs based on their layers. There are many more versions based on functionality and application. PCBs are the heart of any device and must be developed flawlessly.
