Study of the impact of high-voltage trimming on several characteristics of model TFRs and their stability

Peter Ryser, Thomas Maeder, Caroline Jacq, Niklaus Johner

In this work we study in more details the impact of voltage trimming on different characteristics of model thick-film resistors (TFRs). Two series of RuO2-based TFRs with different conducting grain sizes are studied. As the composition of model pastes is c ...

Subsolidus phase equilibria in the PbO-poor part of the TiO2–PbO–SiO2 system and its application in low-temperature thick-film dielectrics

Thomas Maeder, Caroline Jacq, Marko Hrovat

Subsolidus equilibria in the PbO-poor part of the TiO2–PbO–SiO2 diagram were studied with the aim of investigating possible applications for low-temperature thick-film dielectrics. The tie lines are between PbTiO2 and PbSiO3, and between PbTiO3 and SiO2. T ...

Properties and stability of thick-film resistors with low processing temperatures - effect of composition and processing parameters

Claudio Grimaldi, Thomas Maeder, Caroline Jacq, Sonia Vionnet Menot

In this work, the properties (sheet-resistance, temperature coefficient and piezoresistance / gauge factor) and stability of thick-film resistors with low firing temperatures (525...650°C) are studied. To this end, two low-melting lead borosilicate glass c ...
