12 Layer High Speed PCB Megtron M6 2.5mm ENIG Finish Impedance Control

(Custom PCBs are tailored products; the images and specifications provided are for reference only.)


Product Overview

Our 12-Layer High-Speed PCB leverages Panasonic’s Megtron® M6 material to deliver ultra-low signal loss (Dk=3.61, Df=0.004 @10GHz) and precision 50Ω impedance control for 5G, RF, and networking systems. Featuring a 2.5mm thickness, ENIG (Immersion Gold) finish, and resin-filled microvias, this multilayer PCB ensures superior signal integrity, thermal stability (Td 410°C), and HDI (High-Density Interconnect) performance.


Key Features & Benefits

1. High-Frequency Performance
Ultra-Low Loss Material:
Megtron® M6 with Dk=3.61/Df=0.004 minimizes attenuation in high-speed PCBs (>10GHz).
50Ω impedance control on critical layers (L3, L10) for RF/wireless applications.


Advanced PCB Via Technology:
Blind/buried vias (GTL-L2, L3-L8, L3-GBL) and resin-filled microvias (≤0.4mm) for reliability.


2. High-Density & Durable Design:
4/4 mil trace/space and 0.3mm minimum hole size for complex layouts.
12-layer stackup: 5 cores + 6 prepreg layers with 17µm (inner) / 35µm (outer) copper.
5x better through-hole reliability vs. standard FR4; ROHS-compliant for lead-free assembly.


3. Certified Quality
100% electrical tested (zero defects).
IPC-Class-3 certified for aerospace/medical-grade reliability.
