Description
Technical Parameters
Product Introduction
Low Temperature Co-fired Ceramic is an advanced electronic ceramic material produced through ceramic green tape casting, conductor circuit printing, multilayer lamination, and single co-firing at temperatures below 900℃.
Key Advantages
Low Dielectric Loss
LTCC features low dielectric constant and dielectric loss, significantly reducing high-frequency signal attenuation and crosstalk, and improving signal integrity.
Strong Multilayer Integration Capability
LTCC supports the embedding of resistors, capacitors, inductors, and complex conductor lines, enabling three-dimensional circuit design.
Excellent Thermal Stability
The material has a low coefficient of thermal expansion and good dimensional stability, allowing it to withstand long-term high and low temperature cycling.
