Electrical, mechanical and temperature characterization of commercialy available LTCC dielectric materials

Presented paper deals with mechanical, electrical and thermal properties of several commercially available materials that are widely used for fabrication of electronic components, sensor systems etc. In the LTCC (Low Temperature Co-fired Technology). Having complete and accurate information of material chemical composition, its electrical and mechanical properties are essential for successful design of various components and/or systems. In many cases, available technical documentation provided by the manufacturers contains less information than designers require for complete pre-design analysis of system behavior in real time environment. Three offently exploited commercialy available dielectric materials provided by Heraeus company (Heraeus CT700, Heraeus CT707 and Heraeus CT800) are investigated. Electrical, mechanical and thermal properties analyses have been conducted in order to determine some of the important material properties. A full chemical composition analysis was performed resulting in determination of materials' chemical composition, followed with determination of relative permittivity value, elasticity modulus and relative thermal coefficient value.
