Multilayer PCB
Multilayer PCB is a printed circuit board made of more than two layers of copper foil. It consists of an inner copper foil, an insulating substrate and an outer copper foil, and the interconnection between the layers is achieved by drilling and copper plating. Compared with single-layer or double-layer PCBs, multilayer PCBs can achieve higher wiring density and complex circuit design.

Advantages of multi-layer PCBs:

Higher wiring density and complex circuit design capabilities
Better electromagnetic compatibility and signal integrity
Shorter signal transmission paths, improved circuit performance
Higher reliability and mechanical strength
More flexible power and ground distribution

Composition of multi-layer PCBs:

Inner copper foil: Provides conductive layer and wiring
Insulating substrate (FR-4, high-frequency low-loss dielectric, etc.): Isolates and supports each copper foil layer
Outer copper foil: Provides surface wiring and interface
Perforated metallization: Realizes electrical connection between layers
Surface treatment: HASL, ENIG, OSP and other surface treatment processes

Design and manufacture of multi-layer PCBs:

Circuit design: Signal integrity, power/ground integrity design of multi-layer boards
Layout and wiring: Reasonable layer allocation and routing optimization
Process design: Aperture size, layer spacing, copper foil thickness, etc.
Manufacturing process: Lamination, drilling, copper plating, etching, surface treatment, etc.
