We are Ceramic Substrates PCB manufacturer. Rogers curamik® product suite offers best-in-class metallized ceramic substrates that enable higher power efficiency. Our curamik® substrates consist of pure copper bonded or brazed to a ceramic substrate and are designed to carry higher currents, provide higher voltage isolation and operate over a wide temperature range.
Our curamik Ceramic substrates offer high heat conductivity, high heat capacity and thermal spreading of the substrates’ thick copper cladding, making our substrates indispensable to power electronics. The low coefficient of thermal expansion of the ceramic substrate means they outperform substrates based on metal or plastic.
We have bought these types materials from an agent at Rogers Materials company and then process and produce blank circuit boards.
Benefits
- Great heat conductivity and temperature resistance
- High insulation voltage
- High heat spreading
- Low coefficient of thermal expansion outperforms metal or plastic substrates
- Adjusted expansion coefficient enables chip on board
- Efficient processing of master cards and single pieces
- Range of formulations optimized for various power applications
Curamik® Endurance
- Available in multiple ceramic types, including Al2O3 , HPS (ZTA), AlN
- Enhanced reliability performance compared to material combinations of the same dimensions
Our curamik Endurance substrates provide enhanced reliability performance compared to material combinations of the same dimensions. This reliability improvement makes the new substrates well suited for high power applications, such as in EV/HEV, vehicle electrification, general industrial, renewable energy and mass transit. curamik Endurance extends the field of applications for DBC.
