| Summary: | The multilayer inductor is particularly important as a highly stable, easy to use
and miniaturised component in electronic systems, such as radios, VCRs and
computers. There were two main tasks in this research project, one was to
make a proper preparation set-up, and the other was to measure the inductance
and the reciprocal of the Q factor of the multilayer inductors produced. Layers
of ferrite sheets were stacked together with silver layers in between by means
of tape casting method. End metallization was applied to make contact with
the inner conductors. Bulk and multilayered components of the same
dimension were made to undergo parallel conventional sintering. The
experimental work resulted in the complete construction of a tape-casting setup.
The measured L values were in the range of 10⁻¹ to l0⁵ Henries and L fell
rapidly with frequency from 1kHz to 30MHz. The energy was represented by l/Q ranged from 10⁻³ to 10 and also fell rapidly within the same frequency
range. |
