LTCC Technologies

LTCC (Low Temperature Co-fired Ceramic) – technology for the production of multilayer ceramic electro-, radio- and microwave components, modules and boards.

Sample of multi layer module

Primary Advantages of LTCC Technology :

• Firing temperature of 850 °С permits to use materials with low specific resistance , such as silver and gold, instead of molybdenum and tungsten , being used in high-temperature technology;
• Tapes with various features (e.g. working frequency above 30GHz and temperature up to 3500 °С ) can be used as a base of module & board;
• Best heat conduction compared with usual semiconductor circuit boards;
• Capability of creating passive elements E, L and C in the layers, providing modules & boards compactness;
• Each layer is inspected before module assembly and if required, can be changed, increasing product yield;
• High-reliable layer hermiticity ;
• Technological cycles of multi-layer ceramic modules are ecologically clean and compact;
• Manufacturing techniques is relatively simple and less expensive ;
• Many processes can be automated during the serial production ;
• Reduction of manufacturing cycle compared with the usual thick-film technology (parallel processes).
