Product Description

OEM and ODM 4 Layer PCB Board Multilayer Circuit Board Assembly

What's 4 Layer PCB?

A 4-layer PCB is a type of multilayer printed circuit board that consists of four conductive copper layers laminated together with insulating material (typically FR-4). These layers are interconnected through vias (plated holes) to form a complete circuit.

Structure of a 4-Layer PCB:

A standard 4-layer PCB stack-up usually includes:

Top Layer (Signal Layer) - Contains component footprints and signal traces.
Inner Layer 1 (Ground Plane, GND) - Provides a low-impedance return path for signals and reduces EMI.
Inner Layer 2 (Power Plane, VCC) - Distributes power efficiently across the board.
Bottom Layer (Signal Layer) - Additional routing space for signals and components.
