What is a Multilayer PCB and How Does It Work?
A multilayer PCB is a sophisticated circuit board comprising three or more conductive copper layers, including signal layers, internal plane layers, silkscreen overlays, solder mask layers, and more. These layers are laminated together with prepreg (PP dielectric layers) and interconnected through vias, such as plated through holes, blind vias, or buried vias. This construction enables compact, high-density designs for complex electronic systems.
JHYPCB specializes in manufacturing multilayer PCBs with up to 64 layers, catering to industries requiring precision and performance. Learn more about our multilayer PCB fabrication process here.
Key Components of Multilayer PCBs
- Signal Layers: Transmit electrical signals across the board.
- Internal Plane Layers: Provide power and ground planes for stable performance.
- Vias: Enable electrical connections between layers, including through-hole, blind, and buried vias.
- Prepreg and Core: Insulating materials that bond layers together, ensuring durability.
