Multilayer PCB

Multilayer PCB (Multilayer Printed Circuit Board) is a circuit board composed of three or more layers of conductive layers, which are interconnected through internal connection technology to achieve complex circuit design.

Features of Multilayer PCB:

1. High-density integration: Multilayer PCB can achieve more circuit connections in a limited space and improve the integration of circuits.

2. Excellent signal quality: Through reasonable inter-layer layout and signal line design, multi-layer PCB can effectively reduce interference and loss during signal transmission and improve signal quality.

3. Reduce electromagnetic interference (EMI): The design of multi-layer PCB can use the power layer and ground layer as shielding layers to reduce the impact of external electromagnetic fields on the circuit.

4. Improve thermal management performance: By distributing heat sources in different functional layers, multi-layer PCB can effectively dissipate heat and avoid local overheating.

Application fields of multi-layer PCB:

1. Communication equipment: such as smart phones, tablet computers, routers, etc., the high-density integration and excellent signal quality of multi-layer PCB make it the first choice for circuit design in these devices.

2. Automotive electronics: In automotive electronic control systems, multi-layer PCB can realize complex circuit control and signal processing.

3. Medical equipment: In medical electronic equipment, such as electrocardiographs, ultrasound machines, etc., the high-precision signal transmission and processing capabilities of multilayer PCBs have been widely used.

4. Industrial control: In industrial automation and control systems, multilayer PCBs can achieve efficient data acquisition and processing.
