Product Description

4 Layer PCB Flexible Board for Medical Device

 

♦ What is 4 Layer PCB?

 

A ​​4-layer PCB​​ is a printed circuit board with ​​four conductive copper layers​​ stacked together with insulating (dielectric) material in between. These layers are interconnected through ​​vias​​ (plated holes) to create complex circuits while saving space and improving performance compared to single or double-sided boards.

♦ Structure of a 4-Layer PCB​

 

A typical 4-layer stackup consists of:

    1. ​​Top Layer (Signal Layer)​​ – Contains component placements and high-speed signal traces.
    2. ​​Inner Layer 1 (Ground Plane)​​ – Acts as a reference plane for EMI shielding and noise reduction.
    3. ​​Inner Layer 2 (Power Plane)​​ – Distributes stable power supply to components.
    4. ​​Bottom Layer (Signal Layer)​​ – Additional routing space for signals and components.

 

♦ ​​4-Layer PCB vs. 2-Layer PCB​​

Feature 4-Layer PCB 2-Layer PCB
​​Layers​​ 4 (Signal+GND+PWR) 2 (Top+Bottom)
​​Routing Space​​ ✅ High ❌ Limited
​​Signal Noise​​ ✅ Low (GND plane) ❌ Higher
​​EMI Shielding​​ ✅ Better ❌ Poor
​​Cost​​ ⚠️ Higher (~2x) ✅ Lower

 

♦ ​​Manufacturing Process​​

    1. ​​Design​​ – Use CAD tools (Altium, KiCad) to define layer stackup and routing.
    2. ​​Material Selection​​ – Choose core/prepreg materials (FR-4, Rogers).
    3. ​​Lamination​​ – Bond layers under heat/pressure.
    4. ​​Drilling & Plating​​ – Create vias for inter-layer connections.
    5. ​​Etching​​ – Remove excess copper to form traces.
    6. ​​Testing​​ – Verify continuity, impedance, and shorts.
