Abstract

Thick film copper conductors are of considerable interest in thick film industries because of both the potential cost saving compared to the noble metal conductors and the favorable properties in electrical conductivity, solderability, solder leach resistance and wire bondability, However, formation of the excellent copper thick film is a lot complicated due to easily oxidizing property of copper at high temperature. In order to get favorable thick film copper conductor, hybrid microcircuit industry utilizes majorly three kinds of firing atmosphere, such as nitrogen atmosphere, reactive atmosphere and air atmosphere. The processes and the three atmospheres for firing thick film copper conductor were extensively reviewed in this article.
