LTCC Multilayer Substrates KLC
What is LTCC? LTCC stands for Low Temperature Co-fired Ceramics. KOA’s LTCC are multilayer ceramic substrates. This technology permits to use low resistive material as conductor patterns due to the lower temperature needed during firing process compared to general ceramic firing process. This is achieved by adding glass to alumina. KOA uses Silver based paste (Ag) to create the electrical structures in and on the ceramics layers. To be noted, that top and bottom layers patterns can be platted using various processes. Thanks to these materials, low loss electrical performance can be achieved as well as high dimensional accuracy. KOA’s LTCC provides clear advantages for system downsizing by forming surface resistors, inner resistors, and transmission lines on in the substrate. In addition, our thermal expansion coefficient is close to silicon’s one, enhancing the reliability of mounted bare chip.Furthermore, cavity structures can be formed, making possible the creation of low profile packages.
