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.
