What is a Multilayer PCB?

A multilayer PCB is a printed circuit board that combines three or more conductive copper layers separated by dielectric material. This architecture enables compact product designs, stronger electrical performance, and more efficient routing for modern electronics.

Compared with single-sided and double-sided boards, multilayer PCB technology allows higher component density, better signal integrity, better power distribution, and improved EMI control. It is commonly used in applications where size, speed, and reliability are critical.

Typical applications include telecommunications infrastructure, medical devices, aerospace systems, industrial controls, automotive electronics, and advanced computing hardware.
