Product Description

Ceramic substrate is a commonly used electronic packaging substrate material. Compared with plastic and metal substrates, ceramic substrate has the following advantages:


1) Low Dielectric Coefficient and Good Frequency Performance
The low dielectric constant and dielectric loss of ceramic materials can reduce the signal delay time and increase the transmission speed.

2) Good Insulation
Generally speaking, the higher substrate resistance, the better reliability of the package. Ceramic materials are generally covalent bond compounds with better insulation properties.



3) Small Coefficient of Thermal Expansion (CTE)
Covalent bond compounds generally have high melting point, and the higher the melting point, the smaller the thermal expansion coefficient, so the CTE of ceramic materials is generally small.

4) High Thermal Conductivity
Ceramic substrate materials are widely used in high-reliability, high-frequency, high-temperature resistance, and strong air-tight product packaging in aviation, aerospace and military engineering. The packaging of ceramic substrate materials is generally a multilayer ceramic substrate package, which is widely used in hybrid integrated circuit (HIC) and multi-chip module (MCM) ceramic packages.
