Effects of different thermal sintering temperatures on pattern resistivity of printed silver ink with multiple particle sizes

Resistivity is considered a significant parameter for printing a conductive pattern and nano-ink. Nevertheless, the resistivity of a sintered printing pattern varies with the performance of the pattern and nano-ink. The cross section or non-uniformity of the printing pattern is not taken into consid...

Nevertheless, the resistivity of a sintered printing pattern varies with the performance of the pattern and nano-ink.
