Description

FR4 OSP Surface Finishing Process

A Multilayer Printed Circuit Board (PCB) is a sophisticated assembly consisting of three or more conductive copper layers laminated together under high pressure and heat, with insulating materials (such as core and prepreg) separating each layer. Unlike single-sided boards, this complex structure enables high-density wiring and superior signal integrity.


Main Advantages of Multilayer PCB:


1. Enhanced Signal Integrity • Separates signal layers from power/ground layers, reducing crosstalk between adjacent signal traces.
• Provides a dedicated reference plane (ground or power) for signal layers, minimizing signal reflection and transmission loss.
2. Higher Component Density & Space Savings • Allows routing of traces on four layers instead of two, enabling more complex circuit designs in a smaller board area.
• Reduces the need for through-hole vias or jumper wires, making the board layout more compact and suitable for miniaturized devices.
3. Improved Electromagnetic Compatibility (EMC) • Dedicated power and ground layers form a stable "power-ground plane capacitor," filtering out high-frequency noise.
• Isolates sensitive analog signals from noisy digital circuits by placing them on separate layers, reducing electromagnetic interference (EMI) emissions and susceptibility.
4. Cost-Effectiveness for Complex Designs • More economical than 6-layer or higher-layer PCBs when basic 2-layer boards cannot meet performance requirements.
• Lowers overall system costs by reducing the need for additional external components (e.g., noise filters) that compensate for poor signal or EMC performance.



How to order multi-layer boards?

Send us your customizable Files:
1. Gerber files (RS-274X)
2. BOM (if PCBA needed)
3. Impedance requirements & stack-up (if available)
4.Test requirements (TDR, network analyzer, etc.)

Tip:Normally,Gerber files includes: PCB type,thickness, ink color, surface treatment process, and if SMT processing is required, you can provide a component BOM and reference designation diagram, etc.

We’ll reply within 24 hours with a free quote, DFM report, and material recommendation.
