The Influence of Thermal Process on Electrical Conductivity of Microstructures Made by Ink-Jet Painting with the Use of Ink Containing Nano Sized Silver Particles

摘要

The features of the ink containing nano silver sized particles for inkjet printing is presented. After structures printing on substrate, to obtain good electrical conductivity, sintering process is necessary. It was proved, that during heating process, the burning type reaction take place and for this process activation energy of about 1 eV is necessary. This reaction takes important role in electrical resistance decreasing. After sintering process, the conductive structures have typical metallic type properties with TCR of 2080 ppm/K.
