Ceramic substrates are commonly used in power modules and have exceptional thermal, mechanical and electrical properties that make them ideal for demanding power electronics applications. These substrates fulfil the electrical function of the system, provide mechanical stability and excellent thermal performance to meet the requirements of a wide range of unique designs.
Advantages of Ceramic Substrates
ceramic substrates
Ceramic substrates are typically located in the copper/metal composite of power modules and act as part of the power electronics circuit. They help to provide PCB-like functionality and enable them to work well as intended. The diagram below shows typical substrate locations and functions.
Ceramic substrates have many advantages over other metal or plastic based substrates.Rogers curamik ceramic substrates have excellent thermal performance, such as high thermal conductivity, greater thermal capacity and improved heat dissipation.Their low coefficient of thermal expansion enables a number of mechanical advantages to be realised,which makes them suitable for particularly important applications. In addition to this, they have a strong electrical insulation capability,which protects the user from the effects of electrical systems.
Types of ceramic substrates
To optimise the performance of a system, the right substrate must be selected for the application.Our Advanced Electronics Solutions team can help you select the ideal substrate and find the ideal balance between mechanical parameters, thermal performance and cost.
ROGERS' curamik product portfolio includes curamik Power, curamik Power Plus, curamik Thermal and curamik Performance substrates.
