What Is Megtron 7 PCB?
A Megtron 7 PCB is a high-performance printed circuit board fabricated using Panasonic Megtron 7 laminate, an ultra-low loss material developed for high-speed digital and high-frequency signal transmission. Megtron 7 PCBs are widely used in data centers, AI servers, networking equipment, and advanced computing systems where signal integrity is critical.
Compared with conventional FR-4 and standard high-Tg materials, Megtron 7 PCB offers significantly lower dielectric loss, better impedance stability, and superior signal integrity at very high data rates.
Key Material Properties of Megtron 7 PCB
Panasonic Megtron 7 laminate delivers outstanding electrical performance:
-
Dielectric constant (Dk ≈ 3.3–3.4)
Stable Dk supports precise impedance control. -
Ultra-low dissipation factor (Df ≈ 0.001 @ 10 GHz)
Minimizes insertion loss for high-speed signals. -
Excellent thermal reliability
Supports lead-free and high-temperature assembly. -
Low coefficient of thermal expansion (CTE)
Enhances plated through-hole reliability in multilayer designs. -
High glass transition temperature (Tg)
Ensures mechanical stability during fabrication and operation.
These properties make Megtron 7 PCB ideal for advanced digital systems.
