Description de produit

OEM and ODM 4 Layer PCB Board Multilayer Circuit Board Assembly

What Is 4 Layer PCB Board?

A 4-layer PCB is a printed circuit board that contains four conductive copper layers separated by insulating material (typically fiberglass and epoxy resin, like FR4). These layers are laminated together under heat and pressure to form a single, solid board.

Structure of a 4-Layer PCB:

The typical stack-up is:

Top Layer - Signal routing (components often placed here)
Internal Layer 1 - Ground plane (GND)
Internal Layer 2 - Power plane (VCC)
Bottom Layer - Additional signal routing

This configuration helps:

Reduce electromagnetic interference (EMI)
Improve signal integrity
Provide stable power distribution
Allow denser and more complex routing than 2-layer boards

Types of PCB Assembly Services:

Turnkey PCB Assembly: Full service (PCB fabrication + component sourcing + assembly)
Partial (Consignment) Assembly: Customer provides components; the assembler handles soldering
Prototype Assembly: Low-volume assembly for testing designs
High-Volume Production: Mass production for commercial devices
