Multilayer PCB Introduction:
A multilayer PCB (Printed Circuit Board) consists of multiple layers of conductive traces, insulating material, and vias, designed for electronic devices requiring high-density and complex circuitry. Conductive copper traces are etched onto layers of insulating substrate material (typically fiberglass-reinforced epoxy resin), which are stacked and bonded under heat and pressure.
Layers are interconnected using vias - plated-through holes that create electrical connections between different PCB layers. These can be through-hole vias (spanning all layers) or blind/buried vias (connecting specific inner layers).
Multilayer PCB Advantages:
- Higher component density and interconnection capacity
- Reduced circuit size and weight
- Improved signal integrity with reduced EMI and noise
- Enhanced thermal management through heat distribution
Multilayer PCB Types:
- Standard Multilayer PCB: 4-8 layers for general electronics
- HDI PCB: High-density with microvias for compact devices
- Flex/Rigid-Flex PCB: Flexible materials for wearable/medical devices
- Sequential Lamination PCB: 10+ layers for complex designs
- Metal Core PCB: Aluminum/copper core for heat dissipation
- RF/Microwave PCB: Specialized for high-frequency applications
Applications:
- Consumer electronics (smartphones, tablets, laptops)
- Telecommunications equipment
- Automotive electronics and ADAS systems
- Industrial control and automation
- Aerospace and defense systems
- Medical diagnostic equipment
- Power electronics and LED lighting
