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 ...

Low firing temperature thick-film piezoresistive composites : properties and conduction mechanism

Sonia Vionnet Menot

Thick-film technology has found applications on miniaturised hybrid circuits in various fields (automotive electronics, televisions, ...). This technology is also now widely used for the fabrication of force and pressure sensors that use the piezoresistive ...

Tunneling-percolation origin of nonuniversality: Theory and experiments

Peter Ryser, Claudio Grimaldi, Thomas Maeder, Sonia Vionnet Menot

A vast class of disordered conducting-insulating compounds close to the percolation threshold is characterized by nonuniversal values of transport critical exponent t, in disagreement with the standard theory of percolation which predicts t ...

Study of electrical properties of piezoresistive pastes and determination of the electrical transport

Peter Ryser, Claudio Grimaldi, Thomas Maeder, Sonia Vionnet Menot

A vast class of disordered conducting-insulating compounds close to the percolation threshold is characterized by nonuniversal values of transport critical exponents. The lack of universality implies that critical indexes may depend on material properties ...

Low-temperature thick-film dielectrics and resistors for metal substrates

Peter Ryser, Thomas Maeder, Caroline Jacq, Sonia Vionnet Menot

In this work, a set of low-temperature thick-film dielectrics consisting of two high-lead low-temperature glasses, stabilised by various amounts of alumina filler, is characterised on alumina and aluminium metal, as a function of firing temperature. Corres ...
