Abstract

In this work, we report on the conformal laser printing and sintering of Ag nanoparticle inks applied on particularly sensitive substrates and structures. The latter involve challenging patterns with periodicity and aspect ratio in the nano to 100-micron scale. We investigate the effect of a number of essential to the laser sintering technique parameters, such as the laser wavelength, repetition rate, pulse duration and the pulse to pulse spatial and temporal overlap. The demonstrated results show that laser printing and sintering can offer specific solutions to particularly challenging use cases and applications in flexible electronics.
