Abstract

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 four different peak sintering temperatures (885°C, 1000°C, 1100°C and 1200°C) in the frequency range from 300 kHz to 1 GHz. Provided results show significant increase in permeability value with increase of the peak sintering temperature. This increase is followed with increase of losses in the ferrite material and the cut-back of the useful frequency range. In addition, these results can be correlated with results obtained by optical inspection of prepared samples.
