What material is used in Ceramics Substrate?

Ceramic substrates are an integral part of modern electronic devices, and their material selection is crucial. Typically, ceramic substrates are made of high-performance ceramic materials such as aluminum oxide and aluminum nitride. These materials have excellent physical and chemical properties that allow ceramic substrates to perform well in a variety of harsh working environments.

First, alumina is a common ceramic substrate material with excellent high temperature resistance. It can maintain stable physical and electrical properties under extreme temperature conditions and is suitable for the manufacturing of high-temperature electronic equipment. In addition, alumina also has good insulation properties, which can effectively prevent the leakage of current and ensure the stable operation of the circuit. Its corrosion resistance also allows it to maintain excellent performance under harsh environments for long periods of time.

Another common ceramic substrate material is aluminum nitride. Compared with aluminum oxide, aluminum nitride has higher thermal conductivity and mechanical strength, and is suitable for electronic equipment that requires higher heat dissipation performance. The thermal conductivity of aluminum nitride is many times higher than that of aluminum oxide, and it can conduct heat to the external environment more effectively and maintain the normal operating temperature of the equipment. This has led to widespread use of aluminum nitride in high-power electronics and radio frequency applications.

In general, alumina and aluminum nitride are two common ceramic substrate materials. They both have excellent high temperature resistance, corrosion resistance and insulation properties, and are suitable for various harsh working environments. When selecting ceramic substrate materials, comprehensive considerations need to be made based on specific application needs and performance requirements to ensure the stability and reliability of electronic devices.

What size are Ceramics Substrate?

As a key support for electronic components, ceramic substrates’ size diversity is closely related to their flexibility in various application scenarios. Ceramic substrate dimensions can vary depending on specific application needs. From microelectronics to large industrial equipment, ceramic substrates of varying sizes and shapes are possible.

In microelectronic devices, such as smartphones, tablets, and wearable devices, small and highly integrated ceramic substrates are often required. These substrates are usually small in size, able to accommodate multiple electronic components in a limited space, and provide stable support and good heat dissipation. In the industrial field, such as power electronics, automotive electronics and aerospace, large industrial equipment usually requires larger-sized ceramic substrates to meet the layout requirements of complex circuits and high-power electronic components.

The shape of the ceramic substrate also varies depending on the application. In some scenarios, specially shaped substrates are required to accommodate specific installation space or circuit layout requirements. For example, some electronic modules may require round or shaped ceramic substrates to work with other components or to accommodate special physical structures.

In addition to size and shape, the thickness of the ceramic substrate is another important consideration. In some high-density integrated circuit applications, extremely thin ceramic substrates are required to reduce the overall size and improve circuit performance and heat dissipation. In some high-power electronic devices, thicker ceramic substrates may be needed to withstand greater current and heat.

In summary, the size of ceramic substrates varies depending on specific applications, ranging from micro to large, and from standard to special shapes, to meet the needs of various electronic devices. This flexibility makes ceramic substrates an integral part of modern electronics.
