Megtron 6 is a premium high-speed, low-loss PCB laminate developed by Panasonic, designed specifically for next-generation high-frequency and high-data-rate systems. Positioned between standard FR-4 and PTFE-based microwave materials, Megtron 6 delivers exceptionally low transmission loss, stable dielectric performance, and robust thermal reliability—making it a preferred choice in telecom, networking, data-center, computing, and RF applications.
By combining advanced resin chemistry with reinforced glass structures, Megtron 6 offers PTFE-level signal integrity with significantly better manufacturability, cost efficiency, and multilayer process compatibility.
Key Electrical Properties of Megtron 6
1. Ultra-Low Dielectric Dissipation Factor (Df ≈ 0.002)
A material’s dissipation factor indicates its energy loss. With a Df around 0.002, Megtron 6 minimizes dielectric loss—critical for applications operating above 10 GHz or requiring long-distance high-speed channel performance (25G/50G/100G/400G).
Low Df enables:
-
Higher signal fidelity
-
Minimal insertion loss
-
Improved eye-diagram performance
-
Longer trace lengths without repeaters
2. Stable Dielectric Constant (Dk ≈ 3.7)
The Dk of 3.7 ensures predictable transmission line impedance and reduces signal distortion. Its stability over frequency and temperature makes Megtron 6 ideal for:
-
SerDes architectures
-
Differential pairs
-
RF/microwave structures
-
High-speed backplanes
Compared with PTFE, Megtron 6 provides easier processing and tighter Dk tolerance across the panel.
3. Low Transmission Loss
High-speed PCBs must minimize loss from both dielectric and conductor effects. Megtron 6 uses:
-
ultra-smooth copper foils
-
advanced epoxy resin systems
-
optimized glass weave structures
These work together to significantly reduce:
-
insertion loss
-
skin-effect-induced conductor loss
-
skew from glass-weave effects
This is critical for 112G PAM4 networks, 5G transceivers, and HPC systems.
High Thermal Performance and Process Reliability
Megtron 6 is engineered for robust thermal endurance, meeting the growing demands of lead-free soldering, multilayer lamination cycles, and extreme-temperature environments.
Thermal advantages include:
-
high decomposition temperature (Td)
-
strong T260/T288 performance
-
superior CAF resistance
-
reliable through-hole plating (PTH) durability
These factors are essential for PCB stackups exceeding 20–30 layers or high-speed HDI architectures.
Environmental Compliance
Megtron 6 meets:
-
RoHS requirements
-
Halogen-free options
-
strict harmful-substance limitations
This ensures compatibility with global environmental regulations and safe use in industrial, aerospace, and consumer markets.
