What Is Megtron 6? Ultra-Low Loss High-Speed PCB Material

Megtron 6 is a premium ultra-low loss high-speed PCB substrate, serving as the industry standard material for high-frequency, high-speed digital and HDI multilayer circuit designs. Equipped with low Dk glass cloth (R-5775) and matched prepreg (R-5670), Megtron 6 features extremely stable dielectric performance across broadband frequency bands, perfectly catering to high-speed signal transmission demands for networking, mobile communication and wireless devices.

With ultra-low dielectric constant and dissipation factor, Megtron 6 effectively reduces high-speed signal loss and transmission latency. It delivers excellent thermal stability, low thermal expansion coefficient and superior moisture resistance, maintaining stable physical and electrical properties under high-temperature soldering and long-term high-load operation. Supporting HDI high-density interconnection design and standard industrial processing workflows, Megtron 6 is the preferred substrate for high-end high-speed multilayer PCB applications.

Megtron 6 Processing & Storage Guidelines

Megtron 6 laminates and prepregs require standardized storage and processing procedures to retain optimal ultra-low loss performance and structural stability. Flat storage in a cool and dry environment is mandatory to avoid bending and surface scratching. Prepreg needs storage conditions below 23℃ and 50% RH, with long-term storage at 5℃ low temperature. Exposed prepreg cumulative open-air time cannot exceed 8 hours to prevent moisture absorption and performance attenuation.

Inner layers adopt professional chemical cleaning and oxide treatment. Peroxide/sulfuric acid organic coating treatment is preferred to ensure stable interlayer bonding strength. Complete moisture removal drying treatment at 105℃ for 20-30 minutes effectively eliminates surface and internal moisture, ensuring high lamination quality and long-term PCB reliability.
