Integrated cavities, screen-printed passive components and channels are common parts of 3D micro-fluidic devices fabricated in low temperature co-fired ceramics (LTCC) technology. However, realization of defect-free structures without cracks, sagging of cavities or channels is challenging and strongly influenced by quality of lamination and firing processing conditions. Lamination technique based...
In this paper the possibility of detection presents of various liquids in distilled water by employing the interdigital capacitor was investigated. Quantity detection principle of known liquid in distilled water is based on immerging the interdigital capacitor in distilled water and observing changes of its capacity with quantity increment of known liquid. Experimental measurement were done with interdigital...
This paper offers new results of material characterization of ferrite LTCC (Low Temperature Co-fired Ceramic) tape and deals with determination of its magnetic properties. Affects of processing parameters variation (firing profile) on properties of ferrite LTCC tape are determined for the commercially available ESL40011 tape. Obtained results provide information for complex permeability values for...
This paper presents design, simulation, fabrication and experimental characterization of the platinum micro-heater elements built on alumina substrate. Micro-heaters are designed for application where the device has to be heated up to 700 °C in less than a 200 ms. Choosing the proper combination of electrical, thermal and mechanical characteristics of thick film heating resistor, glass layer and substrate,...
Behavior investigation of Low Temperature Co-Fired Ceramic(LTCC) tape when placed in water environment is presentedin this paper. As addition, influence of number of LTCC tapes on overall capacitance. of interdigitalcapacitor (IDC) was also investigated and presented. Acting as a sensing structureIDC was embedded inside LTCC stack to prevent direct contact of water and IDC. LTCC structures with two...
