The evolution of the mechanical properties of low temperature co-fired ceramics fired at different temperatures

The effect of the firing temperature of DuPont 951 LTCC material on some mechanical properties was studied. The nominal firing temperature for this LTCC material is 875 °C. The increase in the elastic moduli of the samples fired between 800 °C and 850 °C from 100 GPa to 122 GPa and in characteristic biaxial strengths from140 MPa and 224 MPa was measured. The samples fired between 875 °C and 1000 °C exhibited higher values of the strength, ranging between 283 MPa and 335 MPa and lower flexural strength.

Investigations of thic K-film piezoresistors terminated with silver-based thick-film conductors

In the paper the investigation of two thick-film resistor materials for application in piezoresistive pressure sensor were presented. Resistors are terminated with low-cost silver based thick film conductive materials. The characteristic of thick-film resistors on LTCC and alumina substrates were evaluated.

Lead-free thick-film resistors on slumina and LTCC substrates

Many investigators reported on investigations of the characteristics of experimental (“home made”) lead-free thick-film resistor materials. However, at least to the authors’ knowledge, there are no articles on testing commercial lead free resistors. In the paper the results of commercial thick-film lead-free resistors with nominal sheet resistivities 10 kohm/sq. were reported. X-ray diffraction (XRD) analysis was used to determine the conductive phase and electrical characteristics were measured.
