Multilayer PCBs are the PCB types that have 3 or more layers. They are preferred when the design demands can not be fulfilled by double-sided PCBs. Devices with more computing power such as PC mainboards, cell phones, telecommunication devices, etc., require multilayer PCB designs that allow running complex ICs and processors.

When starting a new printed circuit board design, you may spend most of your time focusing on the circuit design and component selection. However, the design might translate poorly from the digital domain to physical reality without a guideline provided by your PCB manufacturer. We have prepared a guideline for you to make the right decisions at the design stage from the very beginning.
