Messi Biology states that with the rapid development of 6G communication technology, high frequency, high speed, and high integration have become the core development trends of electronic equipment. As a key substrate material for Printed Circuit Boards (PCBs), the dielectric properties and insulation stability of electronic fibers directly determine the quality of 6G signal transmission. With its unique physical and chemical characteristics, nano magnesium oxide (MgO) has become a core material for the modification of 6G electronic fibers, playing an irreplaceable role in two major dimensions: lowering the dielectric constant and dielectric loss, and enhancing insulation performance while inhibiting ion migration.
The primary advantage of nano magnesium oxide is its excellent low-dielectric performance, which precisely meets the transmission requirements of 6G high-frequency signals. The dielectric constant (Dk) and dielectric loss (Df) are core indicators for measuring the signal transmission capability of electronic dielectric materials; the lower the values, the lower the signal delay and energy loss. Nano magnesium oxide itself has a dielectric constant of only 4–6, which is significantly lower than that of traditional E-glass fibers. By uniformly incorporating it into electronic fibers, the Dk of ordinary E-glass fibers can be significantly reduced from 6.5–7.5 to 4.5–5.5, while simultaneously lowering the dielectric loss. This modification transforms electronic fibers into a “high-speed lane” for 6G signals, effectively reducing attenuation, crosstalk, and distortion during high-frequency transmission. This perfectly matches the stringent requirements for low latency and low loss in 6G base stations, high-speed PCBs, and high-end communication terminals, ensuring stable and high-speed data transmission.
Beyond optimizing dielectric properties, nano magnesium oxide can significantly enhance insulation resistance and fundamentally inhibit ion migration, ensuring the long-term reliability of electronic equipment. Traditional electronic fibers often contain alkali metal oxides such as sodium oxide (Na₂O) and potassium oxide (K₂O). In high-temperature and high-humidity environments, alkali metal ions are prone to migration, which can lead to insulation failure, short circuits, or even component burnout. As an alkaline earth metal oxide, nano magnesium oxide is chemically stable and can replace the alkali metal components in the fiber, enabling “alkali-free” or “low-alkali” formula designs. It blocks the migration paths of alkali metal ions, greatly increases the volume insulation resistance of the fiber, and prevents electrical failures caused by ion migration. Simultaneously, it enhances the fiber’s resistance to heat, humidity, and aging, thereby extending the service life of PCBs and electronic devices.
In the 6G industry chain, electronic fibers are the foundational material for Copper Clad Laminates (CCL) and PCBs. The application of nano magnesium oxide improves the core performance of these base materials from the source. With its triple advantages of low dielectricity, high insulation, and anti-ion migration, nano-magnesium oxide-modified electronic fibers not only meet the technical demands of 6G communications but also adapt to the high-frequency and high-speed material requirements of 6G pre-research, artificial intelligence, and automotive electronics. As a key additive in the field of new electronic materials, nano magnesium oxide is driving the upgrade of electronic fibers from traditional general-purpose types to high-end specialized types, building a solid material foundation for the development of 6G and next-generation communication technologies.
