Researchers have documented the effects of near-infrared (N-IR) heating on the structure and performance of printed silver nanoparticle inks.
metal nanoparticle inks are a great choice for printing low-resistance metal conductors and electrical interconnects. However, after deposition, these inks need to be receded at high temperatures to sinter and increase
. Infrared (IR) heaters are an effective, roll-to-roll compatible method that can apply thermal energy.
effects of near-infrared heating
Now, scientists have characterized the effects of near-infrared (N-IR) heating on the structure and performance of printed silver nanoparticle inks (UTD Ag40x, UT Dots Inc.). A method has been developed to measure the resistance and temperature of printed conductive inks, which are functions of exposure to infrared heaters.
found that the N-IR heater sintered the Ag40x silver sample at maximum strength within 11.6±1.5 minutes (reducing the resistance of the 7 mm print line to 1000 s) and from the highest measured resistance (60M s) to 1000 s. In 2±0.2 minutes, reducing the heater power increases by 1000 s (up to 28.3±2.0 minutes at 80%, but it still takes only 1.9±0.3 minutes to reduce from 60M s to 1000 s.
indicates that sintering progresses rapidly after sintering begins. The SEM image of the ink before and after infrared heating shows microstructure changes associated with sintering and shows the role of reunitors and organic adhesives in preventing sintering.
the study has been published in the Journal of Coating Technology and Research, Volume 16, No. 6.
