What is a Glass Core Package Substrate?

A Glass Core Package Substrate is a type of advanced packaging substrate material that offers unique properties and advantages. Traditional chip packaging substrates mainly use organic materials (such as BT resin) or ceramic materials, whereas glass substrates utilize specially treated glass as the core material. This material possesses several superior characteristics, making it highly suitable for high-performance electronic packaging applications.

Firstly, glass substrates exhibit excellent electrical properties. The dielectric constant and loss factor of glass are relatively low, which helps to improve signal transmission speed and reduce signal loss, making it suitable for high-frequency and high-speed signal transmission needs. Additionally, the thermal expansion coefficient (CTE) of glass is close to that of silicon chips, which helps to reduce the stress between the chip and the substrate during thermal cycling, thereby enhancing the reliability of the packaging.

Secondly, the mechanical properties of glass substrates are also outstanding. Glass materials have higher hardness and rigidity, providing good support and protection, preventing mechanical damage to the chip during operation or use. At the same time, the flatness and surface smoothness of glass substrates are high, which helps to improve the precision and stability of the packaging.

Furthermore, glass substrates have excellent thermal management properties. The thermal conductivity of glass materials is relatively low, which can effectively isolate the heat generated by the chip, preventing heat from transferring to other sensitive components, thereby improving the thermal stability and reliability of the system.

In summary, a Glass Core Package Substrate combines superior electrical, mechanical, and thermal management properties, making it a highly promising high-performance packaging material. As electronic products move towards higher frequency, higher speed, and miniaturization, glass substrates will play an increasingly important role in integrated circuit packaging.
