Multilayer PCB is laminated with three or more different layers of conductive materials,interconnected according to design requirements and connected by metal holes.
The picture above shows the stackup of a 4-Layer/ multilayer PCB.
Core and PP use the same material essentially in the production, but PP is not fully cured, making it more malleable than the core.The alternating layers are then placed into a lamination press.
Extremely high temperatures and pressures are applied to the stackup, causing the PP to “melt” and join the layers together. After cooling off, the hard and solid multilayer board is finished.
Advantages of Multilayer PCBs
- Lower signal delay: The signal transmission path on the multilayer PCB is shorter, the signal delay time is shorter which is especially important for high-speed communication equipment.
- Improve reliability: Multilayer PCB can effectively reduce signal interference and power supply noise through reasonable layout and design and improve the reliability of the entire system.
- Optimize heat dissipation performance: multilayer PCB can be designed with a suitable heat dissipation structure which can effectively improve the heat dissipation performance of the equipment and reduce the failure rate.
- Improve production efficiency: The production process of multilayer PCB can be highly integrated and standardized through automated equipment to improve production efficiency and reduce production costs.
Applications of Multilayer PCBs
There are many fields where multilayer circuit boards are applied in the modern electronics industry, they can be seen everywhere,such as:
∗Remote controllers ∗Digital cameras ∗Tape recorders ∗TV mainboards
∗Mobile phones ∗Washing machines ∗Air conditioners ∗Medical equipment etc.
