Constrained sintering of dielectric and ferrite LTCC tape composites

摘要: Abstract The miniaturisation potential of LTCC devices would be drastically improved, if inductances could directly integrated into the multilayer structure. Co-firing ferrite green tapes in combination with dielectric tapes, which offers this possibility, is focus paper. Commercial tape and a new developed on basis BaFe 12 O 19 were characterised. To manufacture composite structures these two types via technology, must densify at temperatures around 900 °C. characterisation included structure shrinkage behaviour by means density measurements, thermogravimetry, thermomechanical analysis, optical dilatometery microstructure investigations. warpage both single composites was By different constrained sintering generated. Stress effects during cooling cycles related to occurring defects.
