Multi-layer printed circuit boards are more complicated than single-layer or double-layer circuit boards. The multilayer printed circuit board has three or more layers of conductive materials. The other layers, usually copper foil, are stacked on top of the core.
Any layer added after the core is not fully cured. This way, the manufacturer can adjust them relative to the core. After that, the foil continues to advance and can be alternated with other layers through the lamination process. Pressure and high temperature techniques must be used to combine the layers and melt them together safely.
Multi-layer printed circuit boards have many advantages. Overall, these boards are smaller and lighter, which makes them ideal for smartphones or computers, or other products that require multi-functional packaging. Here are some advantages of multi-layer printed circuit boards:
1. Multi-layer printed circuit boards have more functions.
2. High assembly density means that the service life of the circuit board can be prolonged.
3. When connectors for multiple independent circuit boards are not required, the structure will be simpler.
4. Strict testing process at the manufacturing stage means that high-quality and efficient products will be obtained. The electrical characteristics of multi-layer circuit boards are faster than that of single-layer boards. Depending on the number of layers you choose to add, multilayer circuit boards are usually well suited for rigid and flexible structures.

Many industries and products can use and benefit from multilayer printed circuit boards, especially because of their durability, functionality, and lightness. The following are some products that frequently use these boards:
2. Heart monitor
3. Fire alarm
4. GPS and satellite systems
5. Industrial control
