Product Description

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) 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.

2) 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.

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.

Detailed Photos

Ceramic substrate refers to copper foil at high temperature directly bonded to aluminum oxide (Al2O3) or aluminum nitride (AlN) ceramic substrate surface (single or double) special process plate. The ultra-thin composite substrate has excellent electrical insulation performance, high thermal conductivity, excellent soft brazing property and high adhesion strength, and can etch all kinds of graphics just like PCB board, with great current carrying capacity. Therefore, ceramic substrate has become the basic material of high power electronic circuit structure technology and interconnection technology.
