Messi Biology states that low dielectric electronic fiber, usually referring to electronic grade low dielectric glass fiber, is a high-performance electronic material. Magnesium oxide (MgO), as a widely used inorganic material, plays multiple roles in electronic grade low dielectric glass fiber, including improving material performance, reducing costs, and meeting market demands.
The Role of Magnesium Oxide in Low Dielectric Electronic Fibers
- Reducing the dielectric constant: The dielectric constant is a physical quantity that measures the degree of polarization of a material in an electric field. For electronic materials, a lower dielectric constant means less loss and noise during signal transmission. The addition of magnesium oxide can significantly reduce the dielectric constant of glass fibers, thereby improving their performance as electronic materials.
- Improving thermal stability: Electronic devices generate heat during operation. If the thermal stability of the material is poor, it will lead to a decrease in device performance or even failure. The high thermal stability of magnesium oxide enables electronic grade low dielectric glass fibers to maintain stable performance in high-temperature environments.
- Improving mechanical properties: The addition of magnesium oxide can also improve the mechanical properties of glass fibers, such as increasing tensile strength and flexural strength, making electronic grade low dielectric glass fibers less prone to breakage during preparation and improving production efficiency.
- Improving chemical stability: During the preparation and use of electronic devices, materials may be eroded by various chemical substances. Magnesium oxide has good chemical stability and can resist the erosion of various chemical substances, thereby ensuring the long-term performance of electronic grade low dielectric glass fibers.
Applications of Magnesium Oxide in Low Dielectric Electronic Fibers
- Preparation of microcircuit boards (PCBs): In the preparation of microcircuit boards (PCBs), electronic grade low dielectric glass fiber is used as an insulating substrate or surface maintenance material. Its low dielectric constant and high thermal stability enable PCBs to have better reliability and stability. At the same time, the addition of magnesium oxide can also improve the mechanical properties of PCBs and enhance their tensile and flexural resistance.
- Preparation of electronic components such as capacitors and inductors: In the preparation of electronic components such as capacitors and inductors, electronic grade low dielectric glass fiber is used as a dielectric layer or packaging material. Its low dielectric constant and high thermal stability can ensure the stable operation of the components in high-frequency electromagnetic fields and provide good impedance matching. In addition, the addition of magnesium oxide can also improve the chemical stability of the components and extend their service life.
