Conduction Mechanisms in Thick Film Microcircuits
Abstract
Specifications were developed to define good resistors and conductors for the project. The design and performance of a laboratory scale three roll dispersing mill is described. The contact resistance between two single crystals of RuO2 in the presence of glass was measured as a function of temperature and thermal history. After formation of a stable contact during the first firing, the contact resistance was observed to be large compared to the crystal resistance, to have a lower TCR, and to increase with repeated firings; models are proposed to explain these results. The coefficient of linear thermal expansion was measured for alloys in the Ag-Pd and Au-Pt systems; the results were correlated with the respective phase diagrams.
