The Effect of Current Supply Duration during Stepwise Electrical Sintering of Silver Nanoparticles

We studied the effect of current supply duration at final-step currents during stepwise electrical sintering silver (Ag) nanoparticles (NPs). Ag NPs ink was inkjet-printed onto Eagle-XG glass substrates. Constant 0.4 and 0.5 A with various time intervals were applied to printed samples. The damaged line a comparatively shorter duration. On other hand, lower prevented damage longer durations while producing specific resistance. minimum resistances samples sintered 3.59 μΩ∙cm 3.79 μΩ∙cm, respectively. Furthermore, numerical temperature estimation scanning electron microscope (SEM) analysis conducted elaborate on results. results implied that estimated peak helped prevent NP damage. SEM micrographs suggested high surface porosity—caused by higher temperatures—in case resulted in line-specific This contribution is step forward development for electronics applications.
