Bare Ceramic Substrate

Bare Ceramic Substrates refer to ceramic substrates without circuits. They have advantages like high temperature resistance, high electrical insulation performance, low dielectric constant and dielectric loss, high thermal conductivity, good chemical stability, and similar thermal expansion coefficient to components. They are often used as functional ceramic components in various hybrid integrated circuits, high-power modules, smart power semiconductors, automotive electronics, etc. At the same time, the problem we cannot ignore is that the Ceramic Substrate is relatively brittle, its size is limited, and the cost is relatively high.

Currently, the ceramic substrates on the market mainly use high-purity alumina ceramics, aluminum nitride ceramics, Silicon Nitride Ceramics and Silicon Carbide Ceramics as raw materials. Each of them has its own advantages and areas of application. Different types of ceramic substrates have their own advantages and application areas.

At present, we mainly use tape casting or dry pressing forming processes to produce bare ceramic substrates. Our standard thicknesses include 0.25 / 0.30 /0.40 / 0.50 / 0.635 / 0.80 / 1.0mm, etc. In addition, we can provide customers with customized services through secondary processing processes such as laser scribing, laser cutting and precision machining.
